For change_parttype, only GPT-partitioned disks are supported, as I
didn't see an option for sgdisk to make it also work with
MBR-partitioned disks. And while sfdisk could be used instead (or
additionally) it would be a new dependency, and AFAICS require some
conversion of partition type GUIDs to MBR types on our part.
