One doesn't strictly need it. I use it to tell me how near to a full
tape I am using so I reshuffle what goes on which tape when it proves
necessary.

A further point of note is that one should no longer do mounts of tape
devices. For a while now they have been automatically available as
/dev/[n]st[01..] if present on the system. Look it up in the archives
around early to mid-November last year.
