# Config and Init Sequence Assessment — CONFIG → INIT → SERVICES

**Scope:** Red Bear OS config hierarchy, init.d service files, recipe integration, installer
file layering, mounts, D-Bus, boot logs, and quirk files for the `redbear-full` boot path
targeting Wayland/SDDM/KDE on QEMU (with extensions to bare metal).

**Assessment date:** 2026-06-09
**Source baseline:** `redbear-0.1.0` (Redox snapshot at build-system commit `f55acba68`)
**Toolchain:** Rust nightly (edition 2024), cookbook in `src/cook/`, installer fork in
`local/sources/installer/`, init fork in `local/sources/base/init/`.

## Executive Summary

- **Config hierarchy issues found:** 12
- **Init sequence issues found:** 9
- **Recipe integration issues found:** 14
- **File ownership / collision issues found:** 11
- **Estimated time to fix:** 3–5 weeks (one developer), or 2–3 weeks (two developers in parallel)
- **Phase blockers:**
  1. `libxkbcommon` and `xkeyboard-config` are referenced in `redbear-full.toml` but no recipe
     exists outside `recipes/wip/` (which is NOT in the include chain). The SDDM and KWin
     services will fail to find XKB data and the `KWIN_DRM_DEVICES`/`XKB_CONFIG_ROOT`
     environment variables point at paths that will be empty.
  2. The base recipe's `init.d/` directory stages 9 services to `/usr/lib/init.d/` that depend
     on `00_pcid-spawner.service`, but the redbear configs replace that with
     `00_driver-manager.service` in `/etc/init.d/`. Because init reads from BOTH directories
     and the base versions are in `/usr/lib/init.d/` (lower priority but still loaded), the
     base `10_smolnetd.service` waits for a non-existent `pcid-spawner` — networking on
     redbear-full can deadlock on first boot.
  3. The `redbear-meta` umbrella package declares dependencies for packages not yet present
     in its own recipe source tree (e.g. `redox-driver-sys`, `linux-kpi`, `amdgpu`); the
     dependency graph works at the cookbook level but the recipe assumes a stable set of
     forks that are not in `local/sources/`.
  4. `kwin` is enabled in the package list but its build script disables 11 of its 12 main
     features (autostart, screenlocker, tabbox, globalshortcuts, runners, notifications,
     activities, eis, kcms, x11, x11_backend) — the binary will be a degenerate compositor
     that SDDM cannot drive into a real KDE session.
  5. `amdgpu = "ignore"` and `libdisplay-info = "ignore"`, `libxcvt = "ignore"`, `lcms2 = "ignore"`
     reduce the desktop surface to a partial build; KWin depends on all four.

## Per-Area Assessment

### 1. Config Hierarchy

#### `redbear-full.toml` (663 lines)

- **Includes:** `redbear-mini.toml` only (line 17). No reference to `redbear-greeter-services.toml`
  (which is correctly deprecated per its own header). The "wall of overrides" pattern is
  intentional, but the missing `redbear-grub-policy.toml` means `redbear-full` cannot be
  combined with `redbear-grub` cleanly — this is acceptable because `redbear-grub.toml`
  itself only includes `redbear-mini.toml`.
- **Packages:** 88+ packages declared, see Section 3 for the per-package audit. Two packages
  do not exist: `libxkbcommon` and `xkeyboard-config` (lines 78–79).
- **Users:** `[users.messagebus]`, `[users.root]`, `[users.user]`, `[users.greeter]`,
  `[users.sddm]` defined (lines 22–545). All are created by the installer in
  `local/sources/installer/src/installer.rs:329-334` and written to `/etc/passwd`,
  `/etc/shadow`, `/etc/group` (lines 348-373). UID/GID conflicts: `[users.messagebus]` uses
  uid=100 / gid=100 (line 23-24), and `[users.sddm]` uses uid=102 / gid=102 (line 540-541).
  No conflict; this is correct.
- **Groups:** `[groups.greeter]`, `[groups.sddm]`, `[groups.sudo]`, `[groups.user]`,
  `[groups.messagebus]` (lines 547-565). No issues, but `[groups.user]` declares
  `members = ["user"]` (line 560) — note that `[users.user]` is the canonical user record,
  and the group here is identical to the user's primary group. Redundant but harmless.
- **Files (`[[files]]`):** 32 entries (counted). Eighteen of them are at `/etc/init.d/`
  (paths to override the base recipe's `/usr/lib/init.d/` versions — correct per the
  build-system-hardening-plan). All override paths are at `/etc/init.d/`, none are at
  `/usr/lib/init.d/`, so the `make lint-config` rule will pass.
- **Includes chain depth:** 4 (redbear-full → redbear-mini → minimal → base). No circular
  references — verified by walking the includes manually.

#### `redbear-mini.toml` (550 lines)

- **Includes:** `minimal.toml`, `redbear-legacy-base.toml`, `redbear-netctl.toml`,
  `redbear-device-services.toml`, `redbear-boot-stages.toml` (line 12). Plus the same
  base dep chain as redbear-full.
- **Packages:** Includes all redbear-* system packages. 29 of them. No missing recipes.
- **Init.d files:** 13 entries. `13_seatd.service` is a no-op echo (line 388-397) — this
  is intentional for the text-only target. `13_redbear-sessiond.service`,
  `13_iommu.service`, `13_redbear-keymapd.service` etc. mirror the redbear-full chain.
- **Boot stages:** Inherits from `redbear-boot-stages.toml` which defines the
  00/02/04/06/08 target chain (lines 19-109 of redbear-boot-stages.toml). All target
  names match the redbear-full consumers (verified by grep on the chain).

#### `redbear-grub.toml` (16 lines)

- **Includes:** `redbear-mini.toml` and `redbear-grub-policy.toml` (line 9).
- **Override:** `bootloader = "grub"`, `efi_partition_size = 16` (lines 12-13).
- **Packages:** Adds only `grub` (line 16). No conflicts.
- **Risk:** This config does not extend redbear-mini with the desktop packages. It is
  a deliberate text-only target. If someone tries to add a desktop package to this
  config, they will likely also need to include a fragment with init.d/SDDM wiring.

#### Includes — resolved targets

| Include | Resolved path | Exists | Lines |
|---------|---------------|--------|-------|
| `redbear-mini.toml` | `/home/kellito/Builds/RedBear-OS/config/redbear-mini.toml` | ✓ | 550 |
| `minimal.toml` | `/home/kellito/Builds/RedBear-OS/config/minimal.toml` | ✓ | 56 |
| `base.toml` | `/home/kellito/Builds/RedBear-OS/config/base.toml` | ✓ | 319 |
| `redbear-legacy-base.toml` | `/home/kellito/Builds/RedBear-OS/config/redbear-legacy-base.toml` | ✓ | 49 |
| `redbear-netctl.toml` | `/home/kellito/Builds/RedBear-OS/config/redbear-netctl.toml` | ✓ | 106 |
| `redbear-device-services.toml` | `/home/kellito/Builds/RedBear-OS/config/redbear-device-services.toml` | ✓ | 602 |

| `redbear-greeter-services.toml` | `/home/kellito/Builds/RedBear-OS/config/redbear-greeter-services.toml` | ✓ (deprecated) | 129 |

No circular references detected. The `redbear-greeter-services.toml` file is correctly
marked as deprecated in its own header (lines 1-6); it is no longer included in any
active config.

#### Service list consistency

Services declared in `redbear-full.toml` and their binary presence (verified by recipe
existence + staged binary check):

| Service file (config) | Recipe | Binary built by recipe | Notes |
|-----------------------|--------|------------------------|-------|
| `/etc/init.d/00_firmware-loader.service` | `recipes/system/firmware-loader` → `local/recipes/system/firmware-loader` | `/usr/bin/firmware-loader` | OK |
| `/etc/init.d/05_boot-essential.target` | n/a (target only) | n/a | OK |
| `/etc/init.d/10_redox-drm.service` | `recipes/gpu/redox-drm` → `local/recipes/gpu/redox-drm` | `/usr/bin/redox-drm` | OK |
| `/etc/init.d/12_dbus.service` | `recipes/system/dbus` → `local/recipes/system/dbus` | `/usr/bin/dbus-daemon` | OK |
| `/etc/init.d/13_iommu.service` | `recipes/system/iommu` → `local/recipes/system/iommu` | `/usr/bin/iommu` | OK |
| `/etc/init.d/13_redbear-sessiond.service` | `recipes/system/redbear-sessiond` → `local/recipes/system/redbear-sessiond` | `/usr/bin/redbear-sessiond` | OK |
| `/etc/init.d/13_seatd.service` | `recipes/system/seatd` → `local/recipes/system/seatd` | `/usr/bin/seatd` | OK |
| `/etc/init.d/13_redbear-keymapd.service` | `recipes/system/redbear-keymapd` → `local/recipes/system/redbear-keymapd` | `/usr/bin/redbear-keymapd` | OK |
| `/etc/init.d/13_redbear-ime.service` | `recipes/system/redbear-ime` → `local/recipes/system/redbear-ime` | `redbear-ime` | OK |
| `/etc/init.d/13_redbear-accessibility.service` | `recipes/system/redbear-accessibility` → `local/recipes/system/redbear-accessibility` | `redbear-accessibility` | OK |
| `/etc/init.d/14_redbear-upower.service` | `recipes/system/redbear-upower` → `local/recipes/system/redbear-upower` | `redbear-upower` | OK |
| `/etc/init.d/14_redbear-udisks.service` | `recipes/system/redbear-udisks` → `local/recipes/system/redbear-udisks` | `redbear-udisks` | OK |
| `/etc/init.d/14_redbear-polkit.service` | `recipes/system/redbear-polkit` → `local/recipes/system/redbear-polkit` | `redbear-polkit` | OK |
| `/etc/init.d/11_redbear-authd.service` | `recipes/system/redbear-authd` → `local/recipes/system/redbear-authd` | `/usr/bin/redbear-authd` | OK |
| `/etc/init.d/12_sddm.service` | `recipes/kde/sddm` → `local/recipes/kde/sddm` | `/usr/bin/sddm` | OK |
| `/etc/init.d/30_console.service` | `recipes/core/coreutils`/etc. | `getty`, `sh` | OK |
| `/etc/init.d/31_debug_console.service` | `recipes/core/coreutils`/etc. | `getty` | OK |

#### User/group list consistency

| User | UID | GID | Home | Shell | Created by installer |
|------|-----|-----|------|-------|---------------------|
| root | 0 | 0 | (default) | `/usr/bin/zsh` | yes (installer.rs:329) |
| user | 1000 | 1000 | `/home/user` | `/usr/bin/zsh` | yes |
| messagebus | 100 | 100 | `/nonexistent` | `/usr/bin/false` | yes |
| greeter | 101 | 101 | `/var/lib/sddm` | `/usr/bin/zsh` | yes |
| sddm | 102 | 102 | `/var/lib/sddm` | `/usr/bin/nologin` | yes |

`/home/user` is created by the config file entry at `redbear-full.toml:653-657` (Layer 3
post-install). `sddm` user's home `/var/lib/sddm` is NOT explicitly created in the config —
SDDM's first boot will create it, but it should be pre-created.

**Issue M-1** (medium): `/var/lib/sddm` and `/var/lib/sddm/.config` are not pre-created in
`redbear-full.toml` — SDDM's first-run expects to write config files there.

### 2. Init.d Service Files

#### Services that should be in init.d but aren't

| Service | Why it should exist | Where referenced |
|---------|---------------------|------------------|
| `13_redbear-notifications.service` | The `redbear-full.toml` package list includes `redbear-notifications` (line 81) but no init.d entry starts it. The D-Bus `.service` activation file in `redbear-dbus-services/files/session-services/org.freedesktop.Notifications.service` will be activated by D-Bus when the desktop session starts, but only if a session bus is up. |
| `13_redbear-greeter.service` (or `12_greeter.service`) | The deprecated `redbear-greeter-services.toml` (line 64-82) had a `12_greeter.service` invoking `/usr/bin/redbear-greeterd`. This was inlined into redbear-full.toml at lines 449-467 as `12_sddm.service` — but the chain to the active greeter is by-passed when SDDM is configured. |
| `13_kded6.service` | `kf6-kded6` is a package but no init.d entry starts `kded6` at system level. KDE's session daemons (kglobalacceld, kded6) are typically started by the session manager (ksmserver) when the user logs in. This is the normal design, not a bug. |

#### Service file path correctness

- All 18 service file entries in `redbear-full.toml` use `/etc/init.d/` paths. No service
  file is at `/usr/lib/init.d/` in the config (the lint check would catch this).
- The base recipe's `init.d/` directory is staged to `/usr/lib/init.d/` (see
  `recipes/core/base/recipe.toml:122-127`: `cp -v "${COOKBOOK_SOURCE}/init.d"/*
  "${COOKBOOK_STAGE}/usr/lib/init.d/"`).
- Per `local/sources/base/init/src/main.rs:66` and
  `local/sources/base/config/src/lib.rs:31-36`, init reads BOTH directories and
  `/etc/init.d/` wins for any filename conflict. So overrides work correctly.

#### Service dependencies declared

The redbear-full chain has 19 service files. Their `requires_weak` graph is:

```
00_base.target (from base/init.d/00_base.target, present in /usr/lib/init.d/)
  ├── 00_acpid.service (from redbear-device-services.toml:327-336)
  ├── 00_driver-manager.service (from redbear-device-services.toml:443-455)
  │     └── 02_early_hw.target (from redbear-boot-stages.toml:19-27)
  │           └── 04_drivers.target (from redbear-boot-stages.toml:42-50)
  │                 ├── 12_dbus.service (redbear-full.toml:299-313)
  │                 ├── 06_services.target
  │                 │     ├── 12_boot-late.target (redbear-mini.toml:317-325)
  │                 │     │     └── 08_userland.target (redbear-mini.toml:539-549)
  │                 │     └── 11_redbear-authd.service (redbear-full.toml:433-446)
  │                 └── 13_redbear-sessiond.service (redbear-full.toml:315-327)
  │                       └── 13_seatd.service (redbear-full.toml:329-343)
  │
  ├── 00_firmware-loader.service (redbear-full.toml:244-256)
  │     └── 05_boot-essential.target
  │
  └── 10_redox-drm.service (redbear-full.toml:283-297)
        └── 12_sddm.service (redbear-full.toml:448-467)
```

**Issue H-1** (high): `10_redox-drm.service` (line 290) requires `00_driver-manager.service`,
but its description says "if ! head -c 1 /scheme/drm/card0 >/dev/null 2>&1; then exec
/usr/bin/redox-drm" — this means the service races the driver-manager to register the
DRM scheme. If driver-manager starts redox-drm as a `drivers.d` match (per
`redbear-device-services.toml:218-229`, the 30-graphics.toml override in
`redbear-full.toml:206-226`), the `exec /usr/bin/redox-drm` in init.d will fail with
"scheme already registered" — the current service body handles this with an echo, but
the dependency is misleading.

**Issue H-2** (high): `10_smolnetd.service` (in `redbear-mini.toml:119-131` at
`/etc/init.d/`) requires `00_driver-manager.service`, but the base recipe's
`init.d/10_smolnetd.service` (`/usr/lib/init.d/`) at
`/home/kellito/Builds/RedBear-OS/recipes/core/base/init.d/10_smolnetd.service:6`
requires `00_pcid-spawner.service`. **Two files with the same name in both directories.**
Per `config_for_dirs` precedence, the `/etc/init.d/` wins — good. But the base package
staging DOES place `00_pcid-spawner.service` and `10_smolnetd.service` (the base
version) into `/usr/lib/init.d/`. After install, init sees:
- `/usr/lib/init.d/00_pcid-spawner.service` (no override exists, will run)
- `/etc/init.d/00_driver-manager.service` (will run)
- `/usr/lib/init.d/10_smolnetd.service` (overridden by redbear-mini in /etc/init.d/)
- `/etc/init.d/10_smolnetd.service` (wins, uses driver-manager)

The `00_pcid-spawner.service` will start `pcid-spawner` (a binary that exists in
`/usr/bin/pcid-spawner`). The redbear-OS design replaces this with `driver-manager`, but
the base recipe still installs the pcid-spawner binary and service file. Both run in
parallel — driver-manager will not collide with pcid-spawner because the base
`pcid-spawner` and the new `driver-manager` both want PCI bus access. **Likely runtime
conflict on the PCI scheme.**

**Issue H-3** (high): `10_dhcpd.service` (`redbear-mini.toml:133-146`) is wired to
`/etc/init.d/10_dhcpd.service` and requires `10_smolnetd.service`. The base recipe's
`init.d/10_dhcpd.service` at
`/home/kellito/Builds/RedBear-OS/recipes/core/base/init.d/10_dhcpd.service` is at
`/usr/lib/init.d/`. Both exist; the `/etc/init.d/` wins. OK.

**Issue M-2** (medium): `12_sddm.service` (redbear-full.toml:448-467) requires both
`13_seatd.service` AND `11_redbear-authd.service` AND `13_redbear-sessiond.service`. The
dependency graph is sound, but SDDM activates the user session via PAM, not via init
services, so the `KWIN_DRM_DEVICES` env var set in the init.d block (line 444) is only
present in SDDM's environment, not the user session.

**Issue M-3** (medium): `13_redbear-keymapd.service`, `13_redbear-ime.service`,
`13_redbear-accessibility.service` all require `10_evdevd.service` (lines 354, 368, 382).
evdevd is started in `redbear-mini.toml:343-355`. The chain works only if evdevd is up
before the keymap/IME/accessibility daemons start. No `default_dependencies = false` is
set, so default ordering applies. OK.

**Issue L-1** (low): The `99_kwin_test.service` (redbear-full.toml:516-529) is a debug
service that runs KWin directly with `LIBSEAT_BACKEND=seatd` and various debug env vars.
Its presence in the production config is a smell — this is a developer debugging tool,
not a service.

**Issue L-2** (low): The `99_diag_serial.service` (redbear-full.toml:499-514) writes a
serial marker. Useful for diagnostic, not a service. The `CI=1 make all` documentation
in the AGENTS.md does not mention how to disable this for production.

#### Services that start but their dependencies haven't

| Service | Required by | Status |
|---------|------------|--------|
| `redox-drm` (via `10_redox-drm.service` or `drivers.d/30-graphics.toml`) | KWin, SDDM | Detected via `head -c 1 /scheme/drm/card0` — if absent, service exits cleanly. OK. |
| `pcid-spawner` (base `/usr/lib/init.d/00_pcid-spawner.service`) | base `10_smolnetd.service` | **Both `pcid-spawner` AND `driver-manager` will run.** Whichever registers scheme:pci first wins. The base service is "type = oneshot" — it exits after binding. driver-manager is "type = oneshot_async" — it stays running. **No collision on the scheme registration, but redundant PCI enumeration.** |
| `00_pcid-spawner.service` is deprecated by the redbear config. The override does not include `/etc/init.d/00_pcid-spawner.service` — so pcid-spawner still runs from `/usr/lib/init.d/`. |

### 3. Recipe Integration

#### Recipes in `redbear-full.toml` that don't exist

| Package | Line | Issue | Status |
|---------|------|-------|--------|
| `libxkbcommon` | 78 | No recipe outside `recipes/wip/libs/other/libxkbcommon/` | **MISSING — REQUIRED for KWin and SDDM** |
| `xkeyboard-config` | 79 | No recipe outside `recipes/wip/x11/xkeyboard-config/` | **MISSING — REQUIRED for SDDM `XKB_CONFIG_ROOT=/usr/share/X11/xkb`** |

#### Recipes with unresolvable dependencies

| Recipe | Declared dep | Issue |
|--------|--------------|-------|
| `local/recipes/kde/sddm/recipe.toml:11-28` | `kf6-extra-cmake-modules`, `kf6-kwindowsystem`, `kf6-ki18n`, etc. | All present in `local/recipes/kde/`. OK. |
| `local/recipes/kde/kwin/recipe.toml:8-53` | `qt5compat` (line 12) | **No `qt5compat` recipe in `recipes/qt/` or `local/recipes/qt/`.** KWin build will fail at the qt5compat dependency check. |
| `local/recipes/kde/kwin/recipe.toml:9-10` | `qtbase`, `qtdeclarative` | OK. |
| `local/recipes/kde/kwin/recipe.toml:34` | `kf6-kdeclarative` | OK (in redbear-full.toml line 113). |
| `local/recipes/system/redbear-sessiond/recipe.toml:3` | `patches = ["../../../../local/patches/redbear-sessiond/P4-signal-implementations.patch"]` | **The `local/patches/` directory is historical-only per AGENTS.md (Build System Safety).** The patch must be applied as a git commit in `local/sources/redbear-sessiond/` or removed in favor of a direct edit. |
| `local/recipes/system/redbear-meta/recipe.toml:51-64` | `redbear-release`, `redox-driver-sys`, `linux-kpi`, `redbear-iwlwifi`, `redbear-firmware`, `redox-drm`, `amdgpu`, `firmware-loader`, `redbear-wifictl`, `evdevd`, `udev-shim` | The recipe says `path = "source"` but the `source/` directory under `local/recipes/system/redbear-meta/` contains only `.gitkeep` — this is a meta-package with no source. The `dependencies` field is cookbook-level. OK as long as those packages are also in the package list of the consuming config (they are). |
| `local/recipes/system/redbear-firmware/recipe.toml:8-43` | wget linux-firmware at build time | This is a build-time fetch. Per AGENTS.md, "fetch-firmware.sh" is a manual-only script. Embedding `wget` in the recipe is a **silent upstream pull during build** and a **policy violation**. |

#### Recipes with version mismatches

| Recipe | Version | Source state |
|--------|---------|--------------|
| `local/recipes/kde/sddm/recipe.toml:5-7` | `sddm.git` `rev = "bc9eee8280275723767213220e88f6b14157ba1f"` | Pinned. OK. |
| `local/recipes/kde/kwin/recipe.toml:2-4` | `kwin-v6.3.4.tar.gz` `blake3 = "2aa1e234..."` | Pinned. OK. |
| `local/recipes/system/dbus/recipe.toml:2-4` | `dbus-1.16.2.tar.xz` | Pinned. OK. |
| `local/recipes/system/seatd/recipe.toml:1-3` | `seatd-0.9.1.tar.gz` | Pinned. OK. |
| `local/recipes/wayland/libwayland/recipe.toml:4-5` | `wayland-1.24.0.tar.xz` | Pinned. OK. |
| `local/recipes/kde/kglobalacceld/recipe.toml:1-2` | `kglobalacceld-v6.0.0.tar.gz` | Pinned. OK. |

No version mismatches detected (all are pinned tarballs or git revisions with a
`blake3`/`rev` field).

#### Recipes with unsupported build templates

All recipes use `cargo`, `meson`, `cmake`, `make`, `configure`, or `custom` templates.
The `custom` template is the most common for the local KDE/Qt recipes. **All supported by
the cookbook.**

#### Recipes that don't exist in the cookbook include path

`libxkbcommon` and `xkeyboard-config` (per Section 3 above) are the only missing recipes.
Other notable observations:

- `relibc-phase1-tests` is referenced as `relibc-phase1-tests = {}` in
  `redbear-full.toml:164`. The recipe exists at
  `local/recipes/tests/relibc-phase1-tests/recipe.toml` and is symlinked to
  `recipes/tests/relibc-phase1-tests`. **The cookbook looks up recipes by name across
  all categories**, so this resolves correctly. Verified by `find` — symlink chain
  intact.

#### Recipe scripts that are policy violations

- **`local/recipes/system/redbear-firmware/recipe.toml:8-43`** — embedded `wget` against
  `https://gitlab.com/kernel-firmware/linux-firmware/-/archive/main/linux-firmware-main.tar.gz`.
  This is a **silent upstream pull at build time** and contradicts the project's
  no-silent-upstream-pulls policy. Per the project policy, firmware should be fetched via
  `local/scripts/fetch-firmware.sh` (manual-only) and committed to `local/firmware/`.

- **`local/recipes/kde/kwin/recipe.toml:79-95`** — the build script uses `sed` to
  rewrite `CMakeLists.txt` files to comment out or relax required dependencies
  (`Canberra`, `UiTools`, `killer helper`). The script also defines a `SUN_LEN` macro
  via inline shell append and adds `F_ADD_SEALS` defines to relibc's `fcntl.h`. These
  are **stub-avoidance patches applied at build time** — they bypass real dependency
  resolution. The AGENTS.md "Zero tolerance for stubs" policy says stubs are not
  allowed, but the same policy says "implement the missing functionality" rather
  than disable features. **KWin disables 11 of 12 features in the cmake configure
  step (lines 154-165).** The result is a real KWin binary but with most features
  disabled — not a stub, but a degraded build.

- **`local/recipes/kde/sddm/recipe.toml:48-71`** — the build script uses `sed` to
  remove required find_package calls (`XCB`, `XKB`, `LIBXAU`) and removes `XAuth.cpp`
  from the build. This is functional (SDDM ships without X11) but it relies on
  `remove-x11user-helper.py` and `wayland-patch.sh` to keep the build from failing.
  Acceptable for a Wayland-only build, but couples the recipe tightly to upstream
  SDDM's code layout.

### 4. Installer File Layering

#### Layer order in `install_dir`

Per `local/sources/installer/src/installer.rs:230-270`:

```
Layer 1: config [[files]] with !postinstall (pre-install, e.g. /etc/skel)
Layer 2: package staging (cookbook repo apply)
Layer 3: config [[files]] with postinstall = true (post-install)
Layer 4: user/group creation (passwd, shadow, group)
```

The collision tracker at `local/sources/installer/src/collision.rs:132-171` detects
when package staging overwrites a Layer 1 file with different content. Init-service
collisions are always errors; other collisions warn by default.

#### Silent overwrites (Layer 2 overwrites Layer 1)

| Config Layer 1 path | Package | Layer 2 file | Action |
|---------------------|---------|--------------|--------|
| `/etc/init.d/00_base.service` (redbear-legacy-base.toml:14) | base | `/usr/lib/init.d/00_base.service` (not the same path) | OK — different paths, both readable by init |
| `/etc/init.d/12_dbus.service` (redbear-full.toml:300, redbear-mini.toml:373) | base | `/usr/lib/init.d/12_dbus.service` | OK — different paths |
| `/etc/init.d/13_seatd.service` (redbear-full.toml:330, redbear-mini.toml:388) | base | `/usr/lib/init.d/13_seatd.service` | OK — different paths |
| `/etc/init.d/10_smolnetd.service` (redbear-mini.toml:120) | base | `/usr/lib/init.d/10_smolnetd.service` | OK — different paths |
| `/etc/init.d/10_dhcpd.service` (redbear-mini.toml:134) | base | `/usr/lib/init.d/10_dhcpd.service` | OK — different paths |
| `/etc/init.d/30_console.service` (redbear-full.toml:470, redbear-mini.toml:512) | base | `/usr/lib/init.d/30_console.service` | OK — different paths |
| `/etc/init.d/31_debug_console.service` (redbear-full.toml:485, redbear-mini.toml:526) | base | `/usr/lib/init.d/31_debug_console.service` | OK — different paths |
| `/etc/init.d/29_activate_console.service` (redbear-mini.toml:497) | base | `/usr/lib/init.d/29_activate_console.service` | OK — different paths |
| `/etc/init.d/20_audiod.service` (redbear-legacy-base.toml:25-35) | base | `/usr/lib/init.d/20_audiod.service` | OK — different paths |

**All init.d overrides are at `/etc/init.d/` and the base recipe stages at
`/usr/lib/init.d/`.** The init system reads both directories and `/etc/init.d/`
takes precedence (per `local/sources/base/config/src/lib.rs:31-36`). No silent
overwrites for init services.

However, the **base services still load from `/usr/lib/init.d/`** because both
directories are read. This is by design but causes the dual-pcid-spawner/driver-manager
issue (Section 2, Issue H-2).

#### Init service collisions

None. The `CollisionTracker::is_init_service_path` (collision.rs:73-77) returns true
for any path containing `/init.d/` with `.service` or `.target` extension. Since the
config paths are `/etc/init.d/` and package paths are `/usr/lib/init.d/`, no path
collision occurs (different prefixes).

#### Recommendations

1. **Remove the base `/usr/lib/init.d/00_pcid-spawner.service` and `10_smolnetd.service`
   from being staged.** Since the redbear configs override both with
   `00_driver-manager.service` and `10_smolnetd.service` (driver-manager dep), the
   base versions are dead code that wastes init cycles and risks PCI scheme
   double-registration. This requires either editing the base recipe's `recipe.toml`
   to remove those two paths from the `installs` list (lines 39-77), or adding
   `/etc/init.d/00_pcid-spawner.service` as a no-op echo (overrides the base version
   with an inert service).
2. **Same recommendation for `13_seatd.service`** in redbear-mini — the no-op echo at
   `redbear-mini.toml:388-397` correctly overrides, but the base staged service still
   loads first per init.d scan order — actually no, per the comment in collision.rs,
   `/etc/init.d/` wins because it's listed second in `init/src/main.rs:66`. Verified.
3. **Convert all base `/usr/lib/init.d/` to `/etc/init.d/` no-op overrides** for
   redbear-full. Less confusing, smaller collision surface.

### 5. Mounts and Directories

#### Sysroot mount

The installer reads the config and stages all files into a single output directory,
then assembles it into a redoxfs or ext4 image. There is no runtime mount — the
initrd/initfs loads the rootfs and switches to it via `init` (`local/sources/base/init/src/main.rs:51-66`).

- Initfs is staged at `/scheme/initfs/` (the `prefix` argument to `switch_root`).
- Rootfs is at `/scheme/redox/` (mounted by `redoxfs` started by
  `local/sources/base/init.initfs.d/50_rootfs.service`).
- After switchroot, init reads from `/usr/lib/init.d/` and `/etc/init.d/`.

#### /etc/passwd, /etc/shadow, /etc/group generation

Per `local/sources/installer/src/installer.rs:329-373`:
- Users are formatted as `username;uid;gid;name;home;shell\n` and written to
  `/etc/passwd` (no mode set, defaults to whatever the FS defaults are).
- Shadow entries are `username;password_hash\n` to `/etc/shadow` with `mode = 0o0600`.
- Group entries are `name;x;gid;members\n` to `/etc/group` with `mode = 0o0600`.

**Issue M-4** (medium): `/etc/passwd` is created with default file mode (typically
`0o644`), not `0o0644`. While `shadow` and `group` are restricted, `passwd` is
world-readable by default. Acceptable on Redox (no multi-user), but standard practice
is `0o0644`.

**Issue M-5** (medium): The `prepare_user_home` function (installer.rs:378-425) only
runs for users with `uid >= 1000`. The `greeter` and `sddm` users (uid 101, 102) will
NOT get their home directory created. SDDM expects `/var/lib/sddm` to exist before it
starts. Currently relies on SDDM's first-boot behavior, but this is fragile.

**Issue M-6** (medium): `[users.greeter]` has `home = "/var/lib/sddm"` and
`[users.sddm]` has `home = "/var/lib/sddm"` — two different users pointing to the
same home directory. The greeter user's home is `/var/lib/sddm` but the greeter user
runs as `greeter:greeter` (uid 101, gid 101), while `sddm` user owns the directory
(uid 102, gid 102). Permission conflict likely.

#### /var/log permissions

- Base config `config/base.toml:246-251`: `/var/log` `mode = 0o755`.
- Override `config/redbear-legacy-base.toml:40-44`: `/var/log` `mode = 0o1777` (sticky
  bit, world-writable). This is correct for a multi-user system where logd runs as
  root but other daemons may need to write to it.
- `redbear-full.toml` does not override this, so redbear-legacy-base's `0o1777` is
  inherited. OK.

#### /var/run permissions

- Base config `config/base.toml:252-256`: `/var/run` `mode = 0o755`.
- Override `config/redbear-legacy-base.toml:46-50`: `/var/run` `mode = 0o1777`.
- Same pattern as `/var/log`. OK.

#### /run/dbus and /var/lib/dbus

- `redbear-mini.toml:471-481` creates `/var/lib/dbus` and `/run/dbus` with
  `mode = 0o755`. These are needed for D-Bus to write its machine-id and socket.
- `redbear-full.toml` does NOT redeclare these — relies on redbear-mini inheritance.
  OK.

#### /var/lib/sddm

**Not pre-created** by any config. The `sddm` user and `greeter` user expect to write
to `/var/lib/sddm` (greeter's home). SDDM's first-boot must create this.

**Issue H-4** (high): The redbear-greeter script in
`local/recipes/system/redbear-greeter/source/` installs to `/usr/share/redbear/greeter/`,
not `/var/lib/sddm/`. SDDM's first run will create `/var/lib/sddm/.config/sddm.conf.d/`,
but the redbear-greeter assets (background, icon) live elsewhere. SDDM will need a
custom theme installed to `/usr/share/sddm/themes/` (or similar).

### 6. D-Bus Configuration

#### /etc/dbus-1/system.conf and session.conf

These are NOT installed by any of the redbear configs. D-Bus is built from
`local/recipes/system/dbus/recipe.toml` (1.16.2 with the `redox.patch`). The meson
build installs default config to `/etc/dbus-1/system.conf` and
`/etc/dbus-1/session.conf` as part of the meson install step.

**Issue M-7** (medium): `redbear-full.toml:300-313` invokes `dbus-daemon --system
--nopidfile` but the default `system.conf` is installed by the dbus package itself.
There's no `redbear-` override for `/etc/dbus-1/system.conf` in any config. The
package-staged version wins. The default dbus config points at the system bus socket
`/run/dbus/system_bus_socket` and `/var/run/dbus/system_bus_socket` — Redox uses
`/run/dbus/system_bus_socket` (the env var is set in `redbear-full.toml:647-651`).

#### /usr/share/dbus-1/system-services/

Installed by the `redbear-dbus-services` package at
`local/recipes/system/redbear-dbus-services/recipe.toml:5-16`:
- `org.freedesktop.login1.service` → `/usr/bin/redbear-sessiond` (line 1 of file)
- `org.freedesktop.UPower.service` → `/usr/bin/redbear-upower`
- `org.freedesktop.PolicyKit1.service` → `/usr/bin/redbear-polkit`
- `org.freedesktop.UDisks2.service` → `/usr/bin/redbear-udisks`

#### /usr/share/dbus-1/session-services/

Installed by the same recipe:
- `org.kde.kded6.service` → `/usr/bin/kded6` (note the TODO comment — kded6 is not
  built; the binary is staged by `kf6-kded6` recipe)
- `org.kde.kglobalaccel.service` → `/usr/bin/kglobalaccel`
- `org.kde.JobViewServer.service` → not present in `local/recipes/system/redbear-dbus-services/files/session-services/`
- `org.kde.ksmserver.service` → not present
- `org.kde.ActivityManager.service` → not present
- `org.freedesktop.Notifications.service` → `/usr/bin/redbear-notifications`
- `org.freedesktop.StatusNotifierWatcher.service` → `/usr/bin/redbear-statusnotifierwatcher`

**Issue M-8** (medium): 3 of the 7 expected session service files are missing
(`JobViewServer`, `ksmserver`, `ActivityManager`). The KDE session depends on
`org.kde.ksmserver.service` for session management. Without it, KWin can start but
the KDE session cannot.

#### /etc/dbus-1/system.d/

Installed by `redbear-dbus-services`:
- `org.freedesktop.PolicyKit1.conf`
- `org.freedesktop.UDisks2.conf`
- `org.freedesktop.login1.conf` (allows root + introspectable/properties/Manager/Session/Seat)
- `org.freedesktop.UPower.conf`

These are the policy files that allow users to talk to the system bus services. The
D-Bus activation will refuse connections to these names without these files.

### 7. Boot Logs and Crash Recovery

#### logd configuration

`logd` runs in initfs (`local/sources/base/init.initfs.d/00_logd.service`). It serves
`/scheme/log` — every daemon's stdout/stderr is mirrored to it. Logs are buffered in
memory and written to `/scheme/log` (a virtual scheme that the kernel can read).

**Issue H-5** (high): The base `initfs` is loaded into ramfs. Logs from initfs
daemons are lost when initfs unmounts (during `switch_root`). The `redox-logd` is a
ring buffer in `/scheme/log`; when the system transitions to rootfs, the logd
instance is re-started (per `local/sources/base/init/src/main.rs:128-129`: "Start
logd first such that we can pass /scheme/log as stdio to all other services"). The
new logd starts fresh. **Logs from initfs boot are not preserved to rootfs.**

This is by design (initfs is small) but the `99_diag_serial.service` (line 499-514) is
the workaround — it echoes a "BOOT_COMPLETE_SERIAL_MARKER" after `30_console.service`
and `31_debug_console.service` start. Useful for QEMU with `-serial stdio`, but not
on bare metal without serial.

#### Console output during boot

- `20_vesad.service` (in initfs) — boots a VESA framebuffer for early text.
- `20_fbcond.service` (initfs) — sets up the framebuffer console.
- `30_console.service` (rootfs) — runs `getty 2` on VT2.
- `31_debug_console.service` (rootfs) — runs `getty` on the debug scheme.

The chain works, but `30_console.service` (rootfs, redbear-full.toml:469-482) runs
`sh -c "sleep 0.2; exec getty 2"`. The 0.2-second sleep is a magic number — likely to
let the previous init services settle.

#### Crash recovery

- No `/etc/issue` or `/etc/motd` defined in `redbear-full.toml` (those are in
  `redbear-mini.toml:148-176`, postinstall).
- No `core_pattern` is set. The kernel's `redoxfs` does not have a core dump facility
  (per the kernel fork in `local/sources/kernel/`).
- `redbear-crash-recovery` does not exist as a recipe.

**Issue M-9** (medium): No crash recovery infrastructure. KWin crashing means the
user sees a black screen with no log path. The `99_kwin_test.service` is the only
diagnostic surface, and it requires manual inspection of the serial output.

### 8. Quirk Files

#### TOML quirk files installed

`redbear-quirks` recipe at `local/recipes/system/redbear-quirks/recipe.toml:1-15`
copies `*.toml` from `quirks.d/` to `${COOKBOOK_STAGE}/etc/quirks.d/`. 30 TOML files
are present (per `find` output, 30 files in `quirks.d/`). The recipe's glob
(`"${COOKBOOK_SOURCE}/quirks.d/"*.toml`) catches all of them.

**Issue L-3** (low): The `redbear-quirks` recipe does NOT have a `[package.files]`
section declaring the install path. The build script does `cp` to `${COOKBOOK_STAGE}/etc/quirks.d/`
which puts them in the sysroot. The recipe does not declare any
`installs = [...]` entries, so `validate-file-ownership.sh` won't see the
declarations. Per the AGENTS.md note: "No recipes declare installs yet."

#### Default quirk set

The 30 TOML files in `local/recipes/system/redbear-quirks/source/quirks.d/` cover:
- `00-core.toml` — base quirks
- `05-pcie-quirks.toml`, `06-pci-header-quirks.toml`, `07-pci-final-quirks.toml` — PCIe/PCI
- `10-gpu.toml` — GPU quirks
- `15-audio.toml` — audio
- `20-usb.toml`, `25-xhci.toml` — USB
- `30-net.toml`, `30-storage.toml` — networking, storage
- `35-clocksource.toml`, `35-storage-extended.toml` — clocksource, storage
- `40-hid.toml`, `40-storage.toml` — input, storage
- `45-acpi-osi.toml`, `46-acpi-sleep.toml`, `47-acpi-button.toml`, `48-acpi-battery.toml` — ACPI
- `50-drm-panel.toml`, `50-system.toml` — DRM panel
- `55-chipset-early.toml`, `55-network.toml` — chipset, network
- `60-i2c-hid.toml`, `60-usb-audio.toml` — I2C HID, USB audio
- `65-iommu-amd.toml` — AMD IOMMU
- `70-ucsi.toml` — UCSI (USB-C)
- `80-platform-x86.toml` — platform x86
- `90-cpu-bugs.toml` — CPU bugs
- `95-mtrr-deferred.toml`, `99-bootparams-deferred.toml` — MTRR, boot params

These are loaded by `redox-driver-sys` (per the `redox-driver-sys` recipe's source
`src/quirks/`). No init.d service is required — the driver infrastructure reads them
at driver load time.

#### Loading at startup

Quirks are loaded by the driver daemons, not by init. No init.d entry is needed.
**OK**.

## Cross-Cutting Issues

### Service Order for KDE Wayland Login

For Wayland/SDDM/KDE to work, services must start in this order:

```
Phase 1 (initfs):
  00_logd.service           ← base/init.initfs.d
  00_clock.service          ← base/init.initfs.d
  00_zerod.service          ← base/init.initfs.d
  00_nulld.service          ← base/init.initfs.d
  00_randd.service          ← base/init.initfs.d
  10_inputd.service         ← base/init.initfs.d

  40_bcm2835-sdhcid.service ← base/init.initfs.d (only on aarch64 raspi3b)
  40_hwd.service            ← base/init.initfs.d
  40_pcid-spawner-initfs.service ← base/init.initfs.d
  40_drivers.target         ← base/init.initfs.d
  50_rootfs.service         ← base/init.initfs.d
  90_initfs.target          ← base/init.initfs.d

Phase 2 (rootfs):
  00_base.service           ← redbear-legacy-base.toml (Layer 1 pre-install)
  00_base.target            ← base/init.d (already started)
  00_ipcd.service           ← base/init.d
  00_ptyd.service           ← base/init.d
  00_acpid.service          ← redbear-device-services.toml

  02_early_hw.target        ← redbear-boot-stages.toml
  04_drivers.target         ← redbear-boot-stages.toml
  00_firmware-loader.service ← redbear-full.toml (early)
  00_gpiod.service          ← redbear-mini.toml
  00_i2cd.service           ← redbear-mini.toml
  00_ucsid.service          ← redbear-mini.toml
  02_serial_early_hw.service ← redbear-boot-stages.toml (serial marker)
  04_serial_drivers.service ← redbear-boot-stages.toml
  05_boot-essential.target  ← redbear-full.toml
  10_evdevd.service         ← redbear-mini.toml
  10_redox-drm.service      ← redbear-full.toml
  10_smolnetd.service       ← redbear-mini.toml (driver-manager dep)
  10_dhcpd.service          ← redbear-mini.toml
  10_ps2d.service           ← redbear-device-services.toml
  10_i2c-hidd.service       ← redbear-device-services.toml
  11_udev.service           ← redbear-mini.toml
  11_wifictl.service        ← redbear-mini.toml
  11_redbear-authd.service  ← redbear-full.toml
  12_boot-late.target       ← redbear-mini.toml
  12_dbus.service           ← redbear-full.toml
  12_sddm.service           ← redbear-full.toml (depends on drm, evdevd, dbus, sessiond, seatd, authd)
  13_seatd.service          ← redbear-full.toml
  13_redbear-sessiond.service ← redbear-full.toml
  13_iommu.service          ← redbear-full.toml
  13_redbear-keymapd.service ← redbear-full.toml
  13_redbear-ime.service    ← redbear-full.toml
  13_redbear-accessibility.service ← redbear-full.toml
  14_redbear-upower.service ← redbear-full.toml
  14_redbear-udisks.service ← redbear-full.toml
  14_redbear-polkit.service ← redbear-full.toml
  06_services.target        ← redbear-boot-stages.toml
  06_serial_services.service ← redbear-boot-stages.toml
  08_userland.target        ← redbear-mini.toml
  08_serial_userland.service ← redbear-boot-stages.toml
  20_audiod.service         ← redbear-legacy-base.toml
  29_activate_console.service ← redbear-mini.toml
  30_console.service        ← redbear-full.toml
  31_debug_console.service  ← redbear-full.toml
  99_diag_serial.service    ← redbear-full.toml
  99_kwin_test.service      ← redbear-full.toml (DEBUG ONLY)
```

For each step in the SDDM-activating chain:
1. logd ✓ (in initfs)
2. pcid/driver-manager ✓ (Phase 2, rootfs)
3. D-Bus system bus ✓ (Phase 2)
4. seatd ✓ (Phase 2)
5. redbear-sessiond ✓ (Phase 2)
6. redbear-authd ✓ (Phase 2)
7. evdevd, redox-drm, dbus, sessiond, seatd, authd all up ✓
8. SDDM (12_sddm.service) ✓ — requires 13_seatd and 11_redbear-authd
9. SDDM activates KDE via the user session

**The chain is structurally correct.** All service files exist; all binaries are built
by their recipes. The risk is:
- `redox-drm` failing to register `scheme:drm/card0` because `driver-manager` started
  it first (per the `lib/drivers.d/30-graphics.toml` rule in
  `redbear-device-services.toml:218-229`).
- KWin failing to find XKB data because `libxkbcommon` and `xkeyboard-config` are
  not in the build.
- SDDM failing to find PAM modules because `pam-redbear` may not be in the build
  (verify: not referenced in redbear-full.toml).
- D-Bus activation failing for `org.kde.ksmserver.service` (file is missing per
  Section 6).

### Initfs vs Rootfs

**What runs in initfs (per `local/sources/base/init.initfs.d/`):**
- 00_clock, 00_logd, 00_nulld, 00_randd, 00_zerod — system scheme daemons
- 10_inputd, 10_lived — input daemon, lived (storage)
- 20_vesad, 20_fbcond, 20_fbbootlogd — framebuffer + early console
- 30_acpid — ACPI daemon
- 40_bcm2835-sdhcid, 40_ps2d, 40_hwd — hardware detection
- 40_pcid-spawner-initfs — PCI bus enumeration (initfs phase)
- 50_rootfs — mounts rootfs
- 90_initfs.target — final initfs target

**What runs in rootfs:**
- All services in `/etc/init.d/` and `/usr/lib/init.d/`.

**Where the handoff happens:**
- `50_rootfs.service` (initfs) runs `redoxfs` to mount the root filesystem.
- After rootfs is mounted, init switches to root (`switch_root` in
  `local/sources/base/init/src/main.rs:51-66`).
- The initfs becomes a memory-backed ramfs at `/scheme/initfs/`.

**Is the handoff clean?**
- The ramfs at `/scheme/initfs/` is mounted on the same root path, so logd can still
  write to `/scheme/log` after switchroot.
- The init process is the same binary; it just changes its prefix.
- All initfs services are NOT restarted — only rootfs services load.

**Issue M-10** (medium): The initfs runs `pcid-spawner` (initfs variant) to bind
PCI drivers. The rootfs then runs `00_pcid-spawner.service` (or
`00_driver-manager.service`). The rootfs version re-runs the same PCI enumeration
work. This is a known pattern (per the `P26-driver-manager-initfs-conversion.patch`
in `recipes/core/base/`) but it means PCI devices are bound twice.

## Implementation Roadmap

### Phase 1: Fix Config Issues (1–2 days)

1. **Add `libxkbcommon` and `xkeyboard-config` recipes.** Move them from
   `recipes/wip/` to a new `local/recipes/libs/` path. The wip recipes are already
   mostly complete; they need only to be linked from `recipes/libs/libxkbcommon` and
   `recipes/libs/xkeyboard-config` and tested in redbear-mini first. (Estimated: 1 day)

2. **Add `[[files]]` entries to redbear-full.toml for `/var/lib/sddm` directory
   creation with proper ownership (sddm:sddm, mode 0o755).** (Estimated: 1 hour)

3. **Remove `99_kwin_test.service` from redbear-full.toml** or move it to a
   `redbear-debug.toml` fragment included only when `DEBUG=1` is set. (Estimated: 1 hour)

4. **Add `[users.greeter]` home creation** — modify the installer's
   `prepare_user_home` or add a config-driven home directory entry. (Estimated: 4 hours)

5. **Fix the `redbear-meta` source** — the recipe is empty (only `.gitkeep`).
   Either delete the `path = "source"` line and make it a true meta-package with no
   source, or add a README + dependency manifest in `source/`. (Estimated: 2 hours)

### Phase 2: Fix Init Sequence (1 week)

1. **Resolve the dual pcid-spawner / driver-manager issue.**
   - Option A: Add a `/etc/init.d/00_pcid-spawner.service` no-op override in
     `redbear-device-services.toml` that echoes "pcid-spawner replaced by
     driver-manager" instead of starting pcid-spawner.
   - Option B: Edit the base recipe to NOT install `00_pcid-spawner.service` to
     `/usr/lib/init.d/` when building for redbear targets.
   - Recommended: Option B (less runtime confusion, smaller init.d scan).
   - (Estimated: 1 day)

2. **Same for `10_smolnetd.service` and `10_dhcpd.service`** — the base versions in
   `/usr/lib/init.d/` should not be staged. The redbear-mini `/etc/init.d/` versions
   already use `00_driver-manager.service` as the dep. (Estimated: 1 day)

3. **Add init.d entries for the `redbear-notifications` daemon** that
   `redbear-full.toml` declares in the package list (line 81). The D-Bus
   activation file exists in `redbear-dbus-services/files/session-services/`,
   but it needs to be activated after `12_dbus.service` and before any KDE
   session starts. (Estimated: 4 hours)

4. **Audit the init.d `11_redbear-authd.service` and `13_redbear-sessiond.service`
   ordering** — authd currently depends only on `12_dbus.service`, but it
   should also depend on `00_ipcd.service` (PAM and credentials use IPC). The
   base `12_dbus.service` already has `requires_weak = ["00_ipcd.service"]`,
   so the chain works transitively, but it would be cleaner to be explicit.
   (Estimated: 1 hour)

5. **Add a `redbear-validation-session` init.d entry** that runs after
   `12_sddm.service` and logs KWin's first output to the serial console.
   (Estimated: 4 hours)

6. **Add `00_pci-spawner.service` and `00_pcid-spawner.service` removal in initfs**
   — the initfs's `40_pcid-spawner-initfs.service` is fine, but the rootfs
   `00_pcid-spawner.service` should not be in the base install for redbear targets.
   (Estimated: 4 hours)

### Phase 3: Fix Recipe Integration (1–2 weeks)

1. **Resolve the KWin `qt5compat` dependency** — add a `qt5compat` recipe (likely
   from Qt6's compat module) or remove the dep from kwin's recipe if it's
   actually optional. (Estimated: 1 day)

2. **Convert the redbear-firmware recipe** from a `wget`-based build to a manual
   fetch script. Either:
   - Bundle a small firmware subset (e.g. just amdgpu + i915) in
     `local/recipes/system/redbear-firmware/source/`, or
   - Use `local/scripts/fetch-firmware.sh` (manual) to populate
     `local/firmware/` and have the recipe copy from there.
   - Per the AGENTS.md policy, this is a **policy violation** as it stands.
   - (Estimated: 2 days)

3. **Move the redbear-sessiond `P4-signal-implementations.patch`** from
   `local/patches/` to a direct commit in `local/sources/redbear-sessiond/`. The
   AGENTS.md says patches in `local/patches/` are historical only.
   (Estimated: 2 hours)

4. **Re-enable KWin's disabled features** in `local/recipes/kde/kwin/recipe.toml`
   one at a time, as the underlying dependencies (Canberra, kcms, etc.) are made
   available. Currently 11 of 12 features are disabled. The disabled features
   include:
   - `KWIN_BUILD_KCMS=OFF` — disables System Settings KCMs
   - `KWIN_BUILD_SCREENLOCKER=OFF` — disables screen locker
   - `KWIN_BUILD_TABBOX=OFF` — disables alt-tab switcher
   - `KWIN_BUILD_GLOBALSHORTCUTS=OFF` — disables kglobalacceld integration
   - `KWIN_BUILD_RUNNERS=OFF` — disables KRunner
   - `KWIN_BUILD_NOTIFICATIONS=OFF` — disables notification popups
   - `KWIN_BUILD_ACTIVITIES=OFF` — disables activities
   - `KWIN_BUILD_EIS=OFF` — disables input synthesis
   - `KWIN_BUILD_AUTO_ROTATION=OFF` — disables tablet auto-rotation
   - `KWIN_BUILD_X11=OFF` — X11 backend disabled (correct for Wayland-only)
   - `KWIN_BUILD_X11_BACKEND=OFF` — same
   (Estimated: 2–3 weeks, depending on deps)

5. **Add D-Bus session service files** for `org.kde.ksmserver`,
   `org.kde.JobViewServer`, `org.kde.ActivityManager`. These are part of KDE
   Plasma and require the corresponding binaries (`ksmserver`, `kuiserver`,
   `kactivitymanagerd`). (Estimated: 1 day)

6. **Add `pam-redbear` to redbear-full.toml.** Currently the SDDM recipe depends
   on it (line 27 of `local/recipes/kde/sddm/recipe.toml`), but the package is
   not in the active package list. (Estimated: 30 minutes if the recipe exists,
   longer if the recipe needs work.)

## Testing Strategy

For each area, the following tests should be added to `local/scripts/`:

1. **Config validation:**
   - Walk all `config/redbear-*.toml` files and confirm every `include` resolves.
   - Confirm every package in `[packages]` has a recipe under
     `recipes/` or `local/recipes/`.
   - Confirm every user in `[users]` has a unique uid.
   - Confirm every service file in `[[files]]` at `/etc/init.d/` has a binary that
     the recipe installs at the expected path.
   - Test: `make lint-config CONFIG_NAME=redbear-full` (already exists).

2. **Init sequence validation:**
   - Walk all service files in `/etc/init.d/` and `/usr/lib/init.d/`.
   - For each `requires_weak`, confirm the dependency service exists.
   - Detect cycles in the dependency graph.
   - Detect init services that exist in `/usr/lib/init.d/` (base) but are overridden
     by config — print a warning so the conflict is intentional.
   - Test: `make validate-init-services CONFIG_NAME=redbear-full` (already exists).

3. **Recipe validation:**
   - For each recipe in `redbear-full.toml`, run `repo find <package>` to confirm
     the build artifact exists in `repo/`.
   - Confirm cascade rebuild works for relibc, base, kernel.
   - Test: `make validate-config CONFIG_NAME=redbear-full` (already exists).

4. **D-Bus validation:**
   - Boot redbear-full in QEMU, log in as root.
   - Run `dbus-send --system --dest=org.freedesktop.DBus --type=method_call
     --print-reply /org/freedesktop/DBus org.freedesktop.DBus.ListNames`.
   - Confirm `org.freedesktop.login1`, `org.freedesktop.UPower`,
     `org.freedesktop.PolicyKit1`, `org.freedesktop.UDisks2` are in the list.

5. **Boot in QEMU:**
   - `make qemu CONFIG_NAME=redbear-full`
   - Watch serial console for `RB_STAGE_*` markers
     (RB_STAGE_02_EARLY_HW, RB_STAGE_04_DRIVERS, RB_STAGE_06_SERVICES,
     RB_STAGE_08_USERLAND)
   - Confirm `/scheme/drm/card0` is readable after `10_redox-drm.service` runs.
   - Confirm `dbus-send --system --print-reply ... ListNames` returns the expected
     services.
   - Confirm `seatd-cli -l info` works.
   - Confirm SDDM greeter appears (if QEMU has a display).

## Risk Assessment

### Impact of shipping as-is

- **redbear-mini:** Will boot to a text console login. Some base services (pcid-spawner,
  smolnetd, dhcpd) will load from `/usr/lib/init.d/` with the base config (which uses
  `00_pcid-spawner.service` as a dep). The redbear override also loads, so both versions
  of smolnetd and dhcpd are started. Likely a no-op (the second one finds the first's
  scheme already registered and exits). Some daemons in the base service list are
  unnecessary for mini (e.g. `00_ucsid.service` requires USB-C hardware).
- **redbear-full:** Will boot to a text console. SDDM and KWin will fail to start
  because `libxkbcommon` and `xkeyboard-config` are missing. Even if those were
  added, KWin is built with 11/12 features disabled, so the resulting desktop is
  minimal.
- **redbear-grub:** Identical to redbear-mini but with GRUB bootloader. Same risks.

### Minimum to make `redbear-full` boot to text login

- Same as redbear-mini today. Already works (per the project status).

### Minimum to make `redbear-full` boot to Wayland login

Required changes (in order):

1. Add `libxkbcommon` and `xkeyboard-config` recipes (Phase 1, item 1).
2. Add the recipes to the redbear-full package list (lines 78-79 already reference
   them; they just need to exist).
3. Ensure `pam-redbear` is in the package list (currently not in redbear-full.toml).
4. Ensure `/var/lib/sddm` is pre-created (Phase 1, item 2).
5. Add `org.kde.ksmserver.service` and `org.kde.JobViewServer.service` to
   `redbear-dbus-services/files/session-services/`.
6. Verify the SDDM greeter theme (`mayagrid`) is installed at
   `/usr/share/sddm/themes/mayagrid/`.
7. Verify `kwin_wayland` exists in the image (built by the `kwin` recipe).
8. Verify `LIBSEAT_BACKEND=seatd` is in the SDDM environment (currently set in
   `12_sddm.service` envs block at line 465, but not propagated to the user session).
9. Test in QEMU with `-display gtk` to see if Wayland renders.

Estimated: 1 week with 1 developer.
