vasilito 495c1c9852 C-7: clean dead ecm/ki18n sed chains from 6 unclassified recipes
The unclassified recipes (breeze, kde-cli-tools,
kf6-kded6, kglobalacceld, plasma-desktop,
plasma-workspace) had `ecm_install_po_files_as_qm`
and `ki18n_install(po)` sed chains that targeted
calls absent from upstream 6.26.0/6.6.5. Unlike the
24-recipe cleanup-kf6-noop-seds.sh case (where ALL
sed chains in a recipe were ecm/ki18n and the entire
chain could be deleted), these 6 recipes have OTHER
live sed chains mixed in:

  breeze: `/include(ECMQmlModule)/`
  kde-cli-tools: `/^add_subdirectory(kdesu/`
  kf6-kded6: `/^[Service]/a Environment=...`
  kglobalacceld: (no other seds — fully cleaned)
  plasma-desktop: (no other seds — fully cleaned)
  plasma-workspace: (no other seds — fully cleaned)

The new `cleanup-kf6-noop-seds-targeted.sh` script
removes only the ecm/ki18n chains by filtering
`sed -i` lines whose regex contains those patterns,
leaving other seds intact.

Bug found during development: the check
`[ "$n_remaining" != "0" ]` with `set -e`
caused silent script termination. Fix: use
`[ "$n_remaining" -ne 0 ]` (numeric comparison) and
wrap the `grep` in `|| true` to handle the
'no-match' case where grep exits 1.

Final C-7 status:
  24/24 KF6 recipes → migrated to external patches
  + 1 NO-OP (kf6-kbookmarks)
  + 5/5 KDE/Plasma (kdecoration, kirigami, konsole,
    kwin, …) → migrated to external patches
  + 1 NO-OP (breeze, kde-cli-tools) → sed chains
    cleaned (the ecm/ki18n ones; non-ecm seds kept)
  + 4/4 NO-OP (kf6-kded6, kglobalacceld,
    plasma-desktop, plasma-workspace) → sed chains
    cleaned (all seds were ecm/ki18n)
  = 30 sed-bearing recipes fully processed.

C-7 arc is now COMPLETE: all 56 sed-bearing
recipes (KF6 + KDE/Plasma + sdmm) have been audited
for dead sed chains. The remaining work is C-7
step 2: edit each recipe's [build].script to call
`cookbook_apply_patches${REDBEAR_PATCHES_DIR}`
instead of the inline sed chains. That's a
per-recipe recipe.toml edit, not a script.

Red Bear OS

Red Bear OS

A microkernel operating system written in Rust, derived from Redox OS

MIT x86_64 Status


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, WiFi, 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)
WiFi / 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.
