Doesn't CERN use some modified backend code that changes the vnode magic
for files? I thought I heard this was done for rxosd (or it's
predecessor) or something. A modified on-disk format is not going to
work with vanilla OpenAFS, and as far as I know that's exactly the error
you would get doing it.

If I'm way off, then nevermind, but... that's not a "normal" error to
get. Unfortunately we don't print out what the 'bad' magic was, but if
you copy the files in one of the 'special' directories in /vicepfb (just
find one of the directories named 'special') and make them available,
one of us could see what it is.
