i gather you do not like glabel :)

as you might have guessed from the ad0s3, the disks are gparted.  the
reason that they are also glabeled is that this is on a disk controller
from hell, an hpt 16-port, which seems to occasionally renumber the
drives, for example when one is removed.  so i wanted constant labels.
