Hallo, Chris,
Du meintest am 03.01.13:

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
