[pbs-devel] [PATCH proxmox-backup v15 26/26] api: disks: only return UUID of partitions if it actually is one

[Hannes Laimer]

Some filesystems like FAT don't include a concept of UUIDs.
Instead, tools like blkid tools like blkid derive these
identifiers based on certain filesystem metadata, such as
volume serial numbers or other unique information. This does
however not follow the format specified in RFC 9562[1].
