Is it just me, or does the idea of effectivly changing the owner of file
to an arbitary user (nobody) which is normally used as a 'I can't break
anything' user sound like a bad idea?  It would be a pity if root
suddenly got forgotten and the entire system became owned (at least from
the NT end) by nobody.
