From 91d20b9226ec790fe2e586f60644c23e587949a2 Mon Sep 17 00:00:00 2001 From: Jan De Landtsheer Date: Fri, 22 Aug 2025 16:39:11 +0200 Subject: [PATCH] fix: resolve kernel module installation and packaging issues - 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. --- scripts/install-firmware-minimal.sh | 72 +++++++++++++++++++------- scripts/install-packages.sh | 7 ++- scripts/resolve-module-dependencies.sh | 22 +++++--- scripts/setup-initramfs.sh | 51 ++++++++++++++++-- 4 files changed, 120 insertions(+), 32 deletions(-) diff --git a/scripts/install-firmware-minimal.sh b/scripts/install-firmware-minimal.sh index 82965e3..8da8a2f 100755 --- a/scripts/install-firmware-minimal.sh +++ b/scripts/install-firmware-minimal.sh @@ -12,21 +12,27 @@ mkdir -p "$FIRMWARE_DIR" # Install full linux-firmware temporarily to extract essentials echo " Downloading and extracting linux-firmware package..." cd /tmp -apk fetch linux-firmware -firmware_file=$(ls linux-firmware-*.apk | head -1) -if [ -f "$firmware_file" ];
