Odd behavior of labels on different filesystem types

I have run into an odd behavior in 8-stable that I can't see a reason
for.

If I have a FAT32 formatted removable drive, I get /dev entries for it
as both /dev/msdosfs/LABEL and /dev/ufsid/ID. When I mount the
filesystem, the /dev/ufsid label is removed, but the other two remain.

If I have a UFS filesystem on the disk, I have similar devices except
that the LABEL is /dev/ufs/LABEL. But, when the UFS device is mounted,
the /dev/ufsid/ID AND the /dev/ufs/LABEL devs are both deleted. 

I'm not sure which is "right", but I can't see the reason for the
different behavior and it has caused a fair bit of trouble when working
with gnome-mount as I can't unmount a ufs device. When the
/dev/ufs/LABEL device is created again on the umount, gnome-mount sees a
new device and immediately re-mounts it.

Can this inconsistency be corrected?
