Well, I've partially solved my own problem but don't know how to get
Bacula to do it automatically.

The working sequence of load and eject is as follows:

mtx -f /dev/sg0 load 1
mt -f /dev/nst0 rewind (OR WHATEVER YOU'RE DOING)
mt -f /dev/nst0 offline
mtx -f /dev/sh0 unload 1

The catch seems to be needing the offline command, but how do I get
that into the bacula changer script and where???
