Replace all non-canonical build invocations (bare 'make all/live CONFIG_NAME=', 'scripts/build-iso.sh', 'scripts/run.sh') with the canonical './local/scripts/build-redbear.sh' wrapper. Updated: AGENTS.md, local/AGENTS.md, README.md, docs/README.md, docs/06-BUILD-SYSTEM-SETUP.md, and 6 active local/docs plan files. Archived docs and frozen boot-logs left as-is (historical evidence).

## 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, frozen at release 0.1.0, with added hardware support, filesystem drivers, and a KDE Plasma desktop path.
|
||
|
||
**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
|
||
|
||
## Our Git Server
|
||
|
||
Red Bear OS lives on a self-hosted Gitea instance at **https://gitea.redbearos.org**.
|
||
This is the canonical home for the fork — there is no GitHub / GitLab / Codeberg
|
||
mirror that is authoritative.

|
||
|
||
## Quick Start
|
||
|
||
### Prerequisites
|
||
|
||
Linux x86_64 host with Rust nightly, QEMU, nasm, and standard build tools.
|
||
See the [Redox Build Guide](https://doc.redox-os.org/book/podman-build.html) for full setup.
|
||
|
||
### Build & Run
|
||
|
||
```bash
|
||
# Clone (read-only)
|
||
git clone https://gitea.redbearos.org/vasilito/RedBear-OS.git
|
||
cd RedBear-OS
|
||
|
||
# Authenticated clone (one-off) — supply token via env var, not literal here
|
||
git clone https://vasilito:${REDBEAR_GITEA_TOKEN}@gitea.redbearos.org/vasilito/RedBear-OS.git
|
||
|
||
# Recommended: use the Red Bear wrapper
|
||
./local/scripts/build-redbear.sh redbear-mini # Text-only target
|
||
./local/scripts/build-redbear.sh redbear-full # Desktop-capable target
|
||
|
||
# Boot in QEMU with the resulting image
|
||
make qemu
|
||
```
|
||
|
||
> **Build script:** `local/scripts/build-redbear.sh` is the canonical and only
|
||
> supported build entry point. It handles `.config` parsing, prefix staleness
|
||
> detection, `REDBEAR_ALLOW_PROTECTED_FETCH=1`, pre-cooking critical packages,
|
||
> and source fingerprint tracking. Direct `make` invocations bypass these gates
|
||
> and should not be used. See `AGENTS.md` § Build Commands for full details.
|
||
|
||
### Public Scripts
|
||
|
||
| Script | Purpose |
|
||
|--------|---------|
|
||
| `local/scripts/build-redbear.sh` | **Canonical** build wrapper for redbear-mini/full/grub |
|
||
| `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.

## Contributing
|
||
|
||
Red Bear OS uses a **full fork** model. Upstream Redox sources are frozen and archived. All custom work lives in `local/`:
|
||
|
||
```
|
||
local/
|
||
├── patches/ # Durable changes to upstream source trees
|
||
├── recipes/ # Custom packages (drivers, GPU, system)
|
||
├── docs/ # Integration and planning docs
|
||
└── scripts/ # Build, test, and release tooling
|
||
```
|
||
|
||
We welcome contributions made with or without AI assistance — we care about **quality**, not how the code was produced.
