The labels are removed when the partition is mounted somewhere!
So, you will only see the labels of unmounted partitions/disks in devfs.
See for yourself (commands run on my 8.0-RELEASE-p2 system):
Checking that this partition is labeled;
# tunefs -p /dev/ad6s1a
...
tunefs: volume label: (-L) rootbk
When it is mounted,
# mount=20
...
/dev/ad6s1a on /mnt/bk/root (ufs, local)
there are no labels:
# ls /dev/ufs/* /dev/ufsid/*
ls: No match.
After unmounting
# umount /dev/ad6s1a
# ls /dev/ufs/* /dev/ufsid/*
/dev/ufs/rootbk /dev/ufsid/482e0880cf225c60
Both the label set with tunefs and the ufsid label appear!
Mount it again and the labels disappear again;
# mount /mnt/bk/root
# ls /dev/ufs/* /dev/ufsid/*
ls: No match.
Hope this helps.
Roland
