yikes. I kinda assumed that that wouldn't work with hard links.
Guess it does. Since we're talking about hard links you argument seems
a bit better than mine. :) Wow, with the current action if there was a
publicly writable directory somewhere on a partition anyone could create
some major havoc. :( I wonder if there are any cases where this behavior
would be useful.
