Yes, indeed Unix v5 (fifth edition from 1974, that is _not_ SysV!), does allow root to make hard links on directories. But the seventh edition from 1978 already prohibits it. (sorry, at the moment I don't have a v6 at hand to test it there... ;-)) Every more modern Unix I tried, whether free or proprietary, whether SysV or BSD based, refuses to do this even for root. So I'd think that this case can be safely ignored. I don't know about non unixoid systems, though. cheers sascha --=20 Parents strongly cautioned -- this posting is intended for mature audiences over 18.
