- Fixed resolve-module-dependencies.sh to handle missing modules gracefully - Removed destructive 'set -e' behavior that caused immediate exit on missing modules - Enhanced install-firmware-minimal.sh to handle partial success scenarios - Fixed install-packages.sh to preserve installed kernel modules (was deleting them) - Improved setup-initramfs.sh to ensure modules directory always exists - Now successfully installs 43 essential kernel modules in final initramfs - Fixes 'depmod: ERROR: could not open directory /lib/modules' boot issue All kernel modules (.ko files) are now properly included in the final cpio archive.
