Interesting Marcelo. How long has this been true in 2.6?

I thought I had an amanda problem, and eventually went to virtual
tapes on disk, largely because of this. However, I have to say it is
working better than tapes ever did here. Unforch, that 200GB disk is
certainly a single point of failure I don't relish thinking about...
