Oh, sorry, yeah, i meant subvolume *type* UUIDs, indeed. i.e. like the partition type UUIDs that GPT exposes for every partition. And yupp, this is about discovering automatically where to mount what when just looking at a btrfs volume. > Possibly a snapshot family, that describes multiple subvolumes; and > then use that information for a systemd mount job, it would make fstab > mostly obsolete. Instead of supporting too much flexibility I'd try to focus on collecting the subvolumes by a simple rule, for example: just take the first subvolumes with the right type uuids, or just take the oldest or the newest ones, or so... Anyway, sorry for the confusion!
