Document the native Arch Linux build environment that has been the reference since July 2026. This section explains that build.sh and setup-aur.sh now detect and execute directly on Arch Linux, replacing the previous Windows 11 + WSL setup as the primary reference.
The Windows + WSL path remains functional with automatic fallback from Git Bash but is no longer the reference environment.
Add automatic detection and relaunching of build scripts in an Arch Linux container via podman when running on non-Arch distributions (Fedora, Ubuntu, Debian, etc.).
Key changes:
- Implement host_is_arch() function to detect if running on Arch Linux by checking both pacman availability and /etc/os-release
- When non-Arch host is detected, scripts automatically pull docker.io/library/archlinux:latest and relaunch themselves in rootful podman container with --privileged
- Mount repository at same absolute path inside container so WORK_DIR and out/ directories work transparently
- Set up persistent pacman cache volume (fws-pacman-cache) between runs
- Auto-chown output files back to host user after build completes
- Update pacman config to disable landlock sandbox in containers (similar to WSL workaround)
- Run full pacman -Syu upgrade in container before installing archiso to avoid partial upgrade issues
- Add comprehensive documentation in README about Fedora/non-Arch setup
- Update .gitignore to exclude pkgbuilds/ directory
- Add environnement.md documentation file
