I've long considered this to be "wrong" as well. Forcing root to have to
obey whether something is allowed to be writable by root would close up a
lot of the various holes out there. Of course this creates problems with
things like the traditional "passwd" program that would then have to know
to do a chmod to give root write perms to the password file..
