OK, so I have looked at the web pages you pointed me too`. Let me explain
the way that the existing system works. Using the "backup" config, the
"changer" checks the label on each of the vtapes, till it finds the matching
label on the tape in the drive, or fails to. Assuming case 1 then amanda sets
the "slot" to the slot that matches the label on the tape, and the backup 
begins.

Looks to me like what we have to do in the new design is use chg-rait(?), with
3 devices, one to throw away the parity that we don't need, chg-disk, for
the vtapes, and ?? for the single physical slot tapedrive itself. Does this 
sound right? What changer should we use for the tape?
