Sure? btrfs filesystem label /dev/sdb mylabel works, and then btrfs filesystem label /dev/sdb shows "mylabel". Also: findfs LABEL=mylabel shows "/dev/sdb" blkid /dev/sdb shows (among other data) "LABEL=mylabel" Except for the "btrfs" command: same behaviour as with other filesystems. Especially with CDs and DVDs (which normally don't use partitions). Viele Gruesse! Helmut
