I should have added ownership to the above list.. After looking *very*
closely at ownership, it looks like /usr/bin/rlogin magically changed
owners from root to bin, and this is what caused the problem.
Chown'ing it to root fixes everything.

Thanks to John Kohl <jtk_at_atria.com> for making me look closely at the
ownership of the file. Thanks also to Kim Greer
<klg_at_dec2.mc.duke.edu> for making some helpful suggestions.

I'm still wondering how the file could have changed owners. Is there
some strange quirk about AdvFS that the filesytem is silenty hosed in
strange & hard to find ways after an AdvFS related panic?

Maybe I should start running tripwire.. ;-)
