When the cookbook runs without its ratatui TUI (e.g. `CI=1 repo cook
...` from a real terminal, SSH session, or backgrounded shell), the
only progress output is the per-recipe tail of the build script. The
user has no aggregate '5/15 done' view, no per-phase signal (fetch vs
build vs package), and no elapsed-time.
src/cook/status.rs adds a one-line StatusReporter that fills that
gap. Auto-enables when the TUI is off AND log capture is off AND
stderr is a TTY. Output format:
[05/15] kf6-kio: starting
[05/15] kf6-kio: fetched (3.2s)
[05/15] kf6-kio: built (4m 18s)
[05/15] kf6-kio: done (total 4m 23s)
Cached recipes emit `[NN/MM] recipe: cached` (no phase breakdown).
Writes to stderr via eprintln! so it never gets mixed with the
captured build-script log. The ratatui TUI in run_tui_cook() is
unchanged — this is the parallel status path for non-interactive
cooks.
Wiring: a &mut StatusReporter is created in main_inner's cook loop,
threaded through repo_inner() and the per-phase closures in
src/bin/repo.rs. Two phase emissions per recipe: `fetched` (after
handle_fetch) and `built` (after handle_cook, ONLY when the build
is not cached — cached cooks skip the 'built' emission to avoid
confusion). 6 unit tests cover format_elapsed boundaries, the
disabled no-op path, and phase tracking. Rust test count:
14 -> 20 (all pass in 3.2s).
Verified end-to-end with a real multi-recipe cook:
CI=1 ./target/release/repo cook redbear-statusnotifierwatcher \
redbear-traceroute \
redbear-udisks

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

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.
