Running 2.4.5_p1 on Gentoo Linux (no tape spanning, right?).  Ok, let's
say that all images but the last one have been written to tape.  The last
image to be dumped to tape is too large to fit on the tape remaining.

My assumption is that since amanda knows how long the tape is, it won't
attempt to write the last image to the first tape but use the second tape
to write the last image.  Am I correct in my assumption?  I am still
looking for evidence in the documentation but haven't yet found anything.

The thing is, amanda *doesn't* know how long the tape is. It knows how long you told it the tape is. But what if you're using HW compression and that's just a guess? What if you were being conservative?

Amanda will try to write the image, and only stop trying when it hits EOT.
