When using "search" on EFI systems, we sometimes want to exclude devices
that are not EFI disks, e.g. md, lvm. This is typically used when
wanting to chainload when having a software raid (md) for EFI partition:
with no option, "search --file /EFI/redhat/shimx64.efi" sets root envvar
to "md/boot_efi" which cannot be used for chainloading since there is no
effective EFI device behind.
