New comment by dkwo on void-packages repository https://github.com/void-linux/void-packages/pull/46165#issuecomment-1729869190 Comment: I could add a check for the existence of vmlinuz. (Note that efibootmgr also uses vmlinuz, and secure boot is a uefi feature, afaik.) If one installs sbctl, don't they want to sign new kernels? or what is your concern?
