PARTLABELs would be better when partitions are encrypted but as yet unlocked; maybe also if you're somebody that clones filesystems frequently (because the LABEL and UUID get duplicated). Happily, the OP is not trying to achieve anything out of the ordinary. > The "disk" (any "bunch of blocks", actually: can be an image file for > your VM du jour) has no clue, no label and no ID :-) I don't think you can change the ID information that's displayed by the /dev/disk/by-id/ symlinks, like the World Wide Name. Unless you happen to be the POTUS, of course. Cheers, David.
