echo "Rebuild the initramfs so NVIDIA-only systems shed nouveau's unused GSP firmware"

# omarchy_hooks.conf now filters the kms hook out of HOOKS when the proprietary

# NVIDIA driver handles early KMS and NVIDIA owns every display controller

# (#6790). The settings package deploys that conditional, but nothing rebuilds

# the initramfs for a mkinitcpio drop-in change, so affected machines would

# carry ~100 MB of dead nouveau firmware until their next kernel update.

# Rebuild once, and only where the conditional actually changes the outcome:

# evaluate the installed drop-ins the way mkinitcpio does and check that kms

# dropped out. A user-edited omarchy_hooks.conf (pacman leaves the packaged

# update as a .pacnew) keeps kms and correctly skips the rebuild.
