From a6f1e9026e5d19b50c7c522e30e6f216fc9f8180 Mon Sep 17 00:00:00 2001 From: sommerfeld Date: Fri, 29 May 2026 11:18:16 +0100 Subject: feat(kernel): swap stock linux for linux-lts as fallback kernel Promotes linux-hardened to the sole primary kernel and replaces linux with linux-lts as the safety-net fallback. Rationale: - linux and linux-hardened track the same upstream major version and ship within days of each other, so 'linux' was a poor fallback for the regression class that historically takes out the hardened kernel on this hardware (e.g. checkpoint 026 wake-from-suspend panic). linux-lts lags by weeks/months and is almost always known-good when hardened breaks. - Drop etc/mkinitcpio.d/linux.preset, add linux-lts.preset. Hardened preset header + bootstrap.sh efibootmgr instructions updated accordingly (hardened registered first so it's the default; lts registered as the on-demand fallback). - Also add mkinitcpio-firmware (AUR) to silence the spurious 'missing firmware' warnings during initramfs builds. Manual host-side steps after deploy: paru -S linux-lts linux-lts-headers mkinitcpio-firmware sudo pacman -Rsn linux # or via 'just pkg-apply' undeclared flow sudo rm -f /etc/mkinitcpio.d/linux.preset # chezmoi-deployed, not pkg-owned sudo mkinitcpio -P sudo efibootmgr # add the Arch LTS entries, drop the stock linux ones Note: meta/nvidia.txt still lists 'linux-headers' for nvidia-dkms. That's a per-host concern; flagged for follow-up if any nvidia host moves to the linux-lts world. --- meta/base.txt | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'meta') diff --git a/meta/base.txt b/meta/base.txt index f77b85b..616d22c 100644 --- a/meta/base.txt +++ b/meta/base.txt @@ -18,10 +18,12 @@ dosfstools fwupd iwd kernel-modules-hook -linux linux-firmware +mkinitcpio-firmware linux-hardened linux-hardened-headers +linux-lts +linux-lts-headers lostfiles lshw man-db -- cgit v1.3.1
