	I'm not sure they actually work that much either (random opensuse 12.3 machine).

lrwxrwxrwx 1 root root  9 Feb  3 15:31 /dev/tape/by-id/scsi-3201034d7b4000007
- -> ../../st3
lrwxrwxrwx 1 root root 10 Feb  3 15:31
/dev/tape/by-id/scsi-3201034d7b4000007-nst -> ../../nst1

That is what shows up on my machine with 4 tape drives /dev/st0->st4. Its
because there are 4 devices with the same I_T and different luns. The /dev/st*
and /dev/nst* are correct.

	Oh... I suspect your right. If anyone is using it is probably one off scripts.
