hmm. you lost me. why would we want this? isn't the point of creating
dual arch images that you do not need separate arch-specific iso's
anymore?

also, to solve the ".db.tar.gz" overlap problem, isn't it possible with
aufs to mount multiple folders over each other and define a preference
in case filenames collide so that you get the correct .db.tar.gz?
