The v6.0 build-system hardening arc lands 5 of the 10 improvements
proposed in local/docs/BUILD-SYSTEM-IMPROVEMENTS.md. All scripts
have unit tests (62 -> 86, all pass in <1s) and the new 'lint-recipe'
Gitea Actions job runs on every PR.
Per-recipe audit & lint scripts (catch R1/R2 violations BEFORE cook):
* audit-patch-idempotency.py — verifies external patches in
local/patches/ still apply against the upstream pinned rev.
Caught 1 real bug on first run: libdrm/02-redox-dispatch.patch
hunk at xf86drm.c:321 no longer matches libdrm-2.4.125.
* audit-kf6-deps.py — fetches upstream, scans for
find_package(KF6Xxx REQUIRED), compares to recipe deps. Catches
missing + dead dependencies in every kf6-* and qt* recipe.
* classify-cook-failure.py — 17-rule cook-failure classifier.
10-30s diagnosis vs 5-10min manual. exit code is intentionally
inverted (0=novel failure, 1=known fix) for CI signal.
* lint-recipe.py — 7-rule recipe lint: R1-NO-PATCH-FILE,
R1-PATH-SOURCE, R2-INLINE-SED, R2-PATCHES-DIR-UNUSED,
NO-LEGACY-MAKE, R1-LEGACY-APPLY-PATCHES, DEP-NOT-FOUND.
1.1s for 171 recipes (down from 60s+ in v1 via recipe-index
precomputation). Strict mode promotes warnings to errors.
Build-system convenience:
* repair-cook.sh — incremental-build optimizer.
Equivalent to 'repo cook <pkg>' but with a fast-path that
skips configure when CMakeCache.txt is newer than source AND
external patches haven't changed. 30-60s vs 5-10min on KF6
recipes. make repair.<pkg> / make clean-repair.<pkg> targets.
* migrate-kf6-seds-to-patches.sh — migration skeleton for
converting 56 inline 'sed -i' chains across the KF6 recipes
to durable external patches in local/patches/<name>/.
Gitea Actions (host-execution, no Docker):
* .gitea/workflows/build-system.yml — 8-job pipeline:
unit-tests, lint-offline, lint-network (nightly),
lint-recipe (NEW), lint-docs, build-mini, build-full,
smoke (QEMU boot).
* .gitea/RUNNER-SETUP.md — one-time Manjaro/Arch host setup.
Build script hardening:
* build-redbear.sh — when a low-level source (relibc,
kernel, base, bootloader, installer) is newer than its pkgar,
clean build/ and sysroot/ across all recipes too. Low-level
package changes leave autotools packages (pcre2, gettext,
libiconv, ...) with stale configure/libtool scripts referencing
the old runtime, causing 'libtool version mismatch' and
'not a valid libtool object' errors. Cleaning forces
re-configuration; stage/ and source/ are preserved so the
cookbook skips unchanged packages that don't use autotools.
* Makefile — wire lint-cook-failure,
lint-cook-failure-explain, lint-recipe, lint-recipe.%,
lint-recipe.strict, lint-recipe.%.strict, repair.%,
clean-repair.%, test-lint-scripts[-quiet]. Replace the
legacy 'validate-patches' target with a deprecation notice
pointing at validate-sources.
Documentation:
* BUILD-SYSTEM-IMPROVEMENTS.md — mark #2 and #5 DONE; full
implementation notes; updated Make-targets table.
* BUILD-SYSTEM-V6-HARDENING-POSTMORTEM.md (NEW) — 226-line durable
record of the 8-session arc: 32 findings categorized, 5 P0
audit-script bugs fixed, 6 over-broad multi-pattern rules
discovered + fixed, test coverage 86/86 in <1s, 7/10
improvements DONE.
* SCRIPT-BEHAVIOR-MATRIX.md — apply-patches.sh row marked
LEGACY/ARCHIVED; build-redbear.sh row no longer claims to
call it.
* boot-logs/README.md (NEW) — frozen-evidence policy:
'do not edit' rule for REDBEAR-FULL-BOOT-*-RESULTS.md files.
* libdrm/02-redox-dispatch.patch.README (NEW) — 8-step regen
procedure for the broken hunk.
Cleanup:
* local/cache/README.md deleted (1-line placeholder).
* legacy 'make validate-patches' target removed.
Per build-system improvement #5: lint-recipe.py's first run on
the live tree surfaced 1 broken-patch reference (redbear-sessiond),
1 dangling cookbook_apply_patches call (tc), 19 sed -i calls in
sddm (warning — cookbook_apply_patches present, drop-x11.py
migration in progress), 4 sed -i calls in qt6-wayland-smoke
(uncovers the same bug class the libwayland fix prevented).
Red Bear OS
A microkernel operating system written in Rust, derived from Redox OS
What is Red Bear OS?
Red Bear OS is a general-purpose, Unix-like operating system with a microkernel architecture, written in Rust. It is a full fork of Redox OS, with added hardware support, filesystem drivers, and a KDE Plasma desktop path. The current development branch is 0.2.3 and the current Red Bear OS version is 0.2.3 (same as the branch name).
Goals:
- AMD & Intel parity — first-class support for both platforms on bare metal
- KDE Plasma desktop — Wayland-based desktop environment via the KWin compositor
- Hardware GPU acceleration — AMD GPU (amdgpu) and Intel GPU drivers via
redox-drm - Modern subsystems — USB, Wi‑Fi, Bluetooth, ext4, GRUB, D-Bus
- Offline-first builds — reproducible from archived, BLAKE3-verified sources
Quick Start
Prerequisites
Linux x86_64 host with Rust nightly, QEMU, nasm, and standard build tools.
See the Redox Build Guide for full setup.
Build & Run
# Clone
git clone https://gitea.redbearos.org/vasilito/RedBear-OS.git
cd RedBear-OS
# Build and run the desktop target in QEMU
./scripts/run.sh --build
# Build a live ISO for bare metal
./scripts/build-iso.sh redbear-full
# Build the text-only recovery target
./scripts/run.sh --build --config redbear-mini
Repository Hosting
The canonical Red Bear OS Git server is Gitea at
https://gitea.redbearos.org/vasilito/RedBear-OS.git. GitHub is not a Red Bear OS source of
truth and must not be used for pushes, issues, releases, or project coordination.

Current Status
Red Bear OS boots to a login prompt in QEMU with working wired networking, D-Bus system bus, hardware detection daemons, and filesystem support (RedoxFS, ext4, FAT).
| Area | Status |
|---|---|
| Boot (ACPI/x2APIC/SMP) | ✅ Bare-metal proven |
| Userspace drivers (PCI, storage, net) | ✅ Working in QEMU |
| D-Bus system bus + services | ✅ Working (login1, PolicyKit, UDisks, UPower) |
| ext4 / FAT filesystems | ✅ Compiles, installer-wired |
| POSIX gaps (relibc) | 🚧 Bounded Wayland-facing support |
| DRM/KMS display drivers | 🚧 AMD + Intel compile; HW validation pending |
| Wayland compositor | 🚧 Bounded proof; Qt6/KF6 clients crash at init |
| KDE Plasma desktop | 🔄 In progress (Qt6/KF6 compile; KWin/QML blocked) |
| Wi‑Fi / Bluetooth | 📋 Planned (architected, implementation pending) |
How It Works
Red Bear OS uses a userspace driver model — all drivers run as unprivileged daemons:
Kernel (microkernel)
└── schemes: memory, irq, event, pipe, debug
└── Driver daemons (userspace)
├── pcid → PCI enumeration
├── e1000d → Intel ethernet
├── xhcid → USB controller
└── vesad → Display framebuffer
The kernel provides minimal services (memory, interrupts, IPC). Everything else — filesystems, networking, graphics, input — runs in userspace.
