- Fixed build system to clone source repositories instead of downloading binaries - Enhanced scripts/fetch-github.sh with proper git repo cloning and branch handling - Updated scripts/compile-components.sh for RFS compilation with build-binary feature - Added minimal firmware installation for essential network drivers (73 modules) - Created comprehensive zinit configuration set (15 config files including getty) - Added util-linux package for getty/agetty console support - Optimized package selection for minimal 27MB initramfs footprint - Successfully builds bootable vmlinuz.efi with embedded initramfs - Confirmed working: VM boot, console login, network drivers, zinit init system Components: - initramfs.cpio.xz: 27MB compressed minimal Zero-OS image - vmlinuz.efi: 35MB bootable kernel with embedded initramfs - Complete Zero-OS toolchain: zinit, rfs, mycelium compiled from source
