So I don't think uaing the shorthands are correct. The UUID assignments are available on Wikipedia: https://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_type_GUIDs But the systemd docuemntation has extra UUID definitions: https://man.archlinux.org/man/systemd-gpt-auto-generator.8 And finally, if neither resources has a UUID for a specific architecture, we can still use the 'generic' "Linux filesystem data" UUID 0FC63DAF-8483-4772-8E79-3D69D8477DE4.
