Red Bear OS — microkernel OS in Rust, based on Redox

Derivative of Redox OS (https://www.redox-os.org) adding: - AMD GPU driver (amdgpu) via LinuxKPI compat layer - ext4 filesystem support (ext4d scheme daemon) - ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG) - Custom branding (hostname, os-release, boot identity) Build system is full upstream Redox with RBOS overlay in local/. Patches for kernel, base, and relibc are symlinked from local/patches/ and protected from make clean/distclean. Custom recipes live in local/recipes/ with symlinks into the recipes/ search path. Build: make all CONFIG_NAME=redbear-full Sync: ./local/scripts/sync-upstream.sh
