No, I pretty much shot myself in the foot. It's the first run through
a set of 25 vtapes, and physical tapes. I did an amtape to advance to 
the next vatep position, did an amlabel, and _fogot_ to do an amtape
slot prev, since the nightly amdump script (at present) does an amtape slot 
next.

What I would like to do is replace the amtape slot next in the amdump
wrapper script to something a bit "smarter" that would hunt for
the correct slot in the "changer". Where correct is defiend as the
label that amdump is expecting next (or an unused label), _and_
where teh vtape lable matches what is in the physical tape drive
assuming that that label fits the first critereia.

I can probably write such a thing, but I was hoping that someone
else might have already done sothing here.
