Thanks to the great report from Saurabh Charde, we noticed that the removal command used in the minimal initrd creation for deleting the GPU/DRM drivers wasn't working. Fix that so now GPU drivers aren't included for real (both for space and boot "issue-prone" criteria). Closes: https://gitlab.freedesktop.org/gpiccoli/kdumpst/-/issues/19 Reported-by: Saurabh Charde (@schardev) Signed-off-by: Guilherme G. Piccoli <gpiccoli@igalia.com>
