+Description: unconditionally create grub.cfg on our EFI boot partition
+ When grub is installed to the EFI partition with Secure Boot support, it
+ always needs some config to tell it the prefix to the /boot/grub disk,
+ because we aren't modifying the grub image at runtime to set the root.
+ So even though when using LVM we don't need to search for the root using
+ search.fs_uuid, we do need to use load.cfg to tell grub what that root
+ is.
