I don't see a problem with your changer.  For this amdump,
amanda did not need a second tape.  Everything could fit
on a single tape.  Runtapes doesn't say how many tapes
amanda WILL use, it is how many it CAN use.

However, I'm surprised amanda did an incremental of
/usr when you  have dumpcycle 0.  I expected that to
force full dumps everytime.
