Yeah, disregard the part about NT policy, it was background info that I
thought might help you to understand what I was trying to accomplish;
it's not important to the topic at hand. Let me change the permissions
a bit so as to be more accurate (the second folder was not needed, I
think I might have had something else in mind):
directory | owner | group | perms
topFolder root someGroup 7730
That should work, and it'll make every file owned by root, who will be
the only one who can delete it. Just make sure no one figures out how
to put a shell script in this folder and execute it! ;)
