- Added user mapping (UID:GID) to Docker Compose services to prevent root-owned files
- Export current user's UID/GID in build.sh for Docker Compose
- Enhanced clean build to handle permission issues gracefully:
* Try normal cleanup first
* Fallback to container-based cleanup for root-owned files
* Ultimate fallback to sudo if needed
- Added cleanup for all Docker volumes (build, source, kernel, target caches)
Fixes 'Permission denied' errors when cleaning output files created by Docker containers.
- Added upx package to Dockerfile.alpine build dependencies
- Added optimize_binary() function to compile-components.sh
- Automatically strips debug symbols from all Zero-OS binaries
- Applies UPX compression with --best --lzma for maximum size reduction
- Optimizes binaries in both initramfs and output directories
- Shows size reduction stats (original → stripped → compressed)
- Graceful fallback if UPX fails, keeping stripped version
This significantly reduces initramfs size by compressing zinit, rfs, and mycelium binaries.
- Add openssl-libs-static package to both Dockerfiles
- Add pkgconfig for proper SSL library detection
- Fixes mycelium compilation error with missing -lssl and -lcrypto
- Add cargo to PATH in dev-shell service
- Add target-cache volume for Rust build caching
- Use login shell to properly source cargo environment
- Keeps existing build infrastructure and caching strategy
