Sorry, I'm still confused about that changerfile...is it a file, or just a
text string to be used as the "prefix" for...what? Tape names? In the
wiki above, they show this example:
changerfile "/home/amanda/test/chg-disk-status" # status files prefix
But no example contents for that file.

I used:
tapedev "file:/mnt/usb/dumps"
The example page for chg-disk uses:
tapedev "file:/amandatapes/test/slots"
I assume either should work fine, but still find the distinction between
the "slot" name and the (virtual) tape name a little confusing. Is there
any point in using:
labelstr "^FULL[0-9][0-9]*$"
Like I did for "real tapes", when amanda is going ahead and using "slotN"
for the names of each dmp directory anyway?

According to that wiki, I would think chg-disk (simpler) would be better
for me)

For chg-disk, this parameter is moot, since the file is, correct?
Thanks again, sorry for my density...
