My users.dat file is getting hosed on a regular basis.  I retract
my earlier stupid idea that it had something to do with tar.  I think
it clearly doesn't.  It always happens when someone is logged in (ie,
it lets them in, since their passwd works) and something they
do while in the message area causes users.dat to be completely
emptied -- zip zilch nada.

So when users.dat gets hosed and there are absolutely no users in
it, guess what happens to the next person who logs in?  Well, they
create an account, and whaddya know, they are user #0...
