On my Arch Linux system, udev already has persistent rules for tapes in /dev/tape: $ ls /dev/tape/by-id/ total 0 drwxr-xr-x 2 root root 100 Dec 18 20:45 . drwxr-xr-x 4 root root 80 Dec 18 18:22 .. lrwxrwxrwx 1 root root 9 Dec 19 23:21 scsi-350014380125815e0 -> ../../sg6 lrwxrwxrwx 1 root root 9 Dec 19 23:21 scsi-350014380125815e1 -> ../../st0 lrwxrwxrwx 1 root root 10 Dec 19 23:21 scsi-350014380125815e1-nst -> ../../nst0 sg6 is the autochanger on my system. If your system doesn't have these, and no update to udev is available, maybe you can copy the rules across from a newer version of udev[1]? > Is there another way do make this work?

Nope, this is all part of the udev rule system. Cheers, Adam.
