Yes drive not, but the partition. > Maybe Linux order depends on a race, and is different every time!

But I think it's not that commonly used. If we assume that on multipath and dmraid devices there are no BSD partitions we could just use the partition number in the device filename. Then we don't need to use UUIDs there.
