Migrated sddm (the last lint-recipe erroring
recipe) to use the cookbook_apply_patches helper.
The 19 inline `sed -i` chains in sddm's
[build].script have been captured in
`local/patches/sddm/01-initial-migration.patch`
(122 lines) and replaced with a single
`cookbook_apply_patches "${REDBEAR_PATCHES_DIR}"`
call.
sddm is git-sourced (not tar-sourced), so the
migration script had to:
1. Snapshot the upstream `source/` dir to
`source-pristine/` (the migration script
supports both tar and git sources by using
whatever's in `source/` as the upstream state).
2. Apply all 19 sed chains directly to `source/`.
3. Diff pristine vs post-sed.
4. Save the diff as the migration patch.
The patch covers 19 sed chains targeting:
- 6 single-line edits to CMakeLists.txt (XCB,
XKB, LIBXAU pkg_check, Qt5/Qt6 find_package,
add_subdirectory(test) removal, enable_testing)
- 6 `find -exec` patterns for LIBXCB/LIBXKB/
LIBXAU include-dir stripping across the source
- 1 LIBJOURNALD QUIET pattern
- 1 XAuth.cpp removal
- 1 LIBXAU_LINK_LIBRARIES stripping
- 1 ioctl(TIOCSCTTY) → ioctl(TIOCSCTTY, NULL) fix
- 1 XAuth::writeCookieToFile → true
- 1 #include "XAuth.h" removal
- 1 LibJournald QUIET
End-to-end verified:
`make lint-recipe`: 173/173 recipes clean (was
1 error before this commit). 0 errors.
`make lint-build-system-all`: passes.
Recipe edit script `edit-kf6-recipes-for-patches.sh`
and migration script `migrate-kf6-seds-direct.sh`
both got a one-line addition for sddm.
lint-recipe summary (final, this commit):
173/173 clean, 0 errors, 0 warnings (other than
the 1 pre-existing warning).
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.
Public Scripts
| Script | Purpose |
|---|---|
scripts/run.sh |
Build and run in QEMU (-b to build, -c <config> for target) |
scripts/build-iso.sh |
Build a live ISO for bare-metal boot |
scripts/build-all-isos.sh |
Build all live ISO targets |
scripts/network-boot.sh |
PXE network boot helper |
scripts/dual-boot.sh |
Dual-boot installation helper |
Config Targets
| Target | Type | Description |
|---|---|---|
redbear-full |
Desktop | Wayland + KDE + GPU drivers + D-Bus services |
redbear-mini |
Console | Text-only recovery / install target |
redbear-grub |
Console | Text-only with GRUB boot manager |
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.

Red Bear OS uses a full fork model. Upstream Redox sources are frozen and archived. All custom work lives in local/:
