There are real reasons to overmount a filesystem. It's getting to be
a usability problem, probably because Linux (UNLIKE MOST OTHER UNIXES)
didn't allow it until just recently. This change caused some
problems, including with the automount daemon. I would like to see an
option to mount(8) to allow it, by default disallow by policy.
