You can "down with root" all you want, but as a UNIX user and administrator,
I expect that there will be a deific user; if it goes away, I'll just
create one who belongs to all access groups, myself.

Not that ACLs are _bad_, mind you, IFF we can implement them intelligently
(I don't think such a solution exists, actually).
But "root" is a historical part of UNIX (NetBSD/Trademarks notwithstanding).
I personally don't want to see "root" go away because that would seriously
begin to impede what I do.

On the other hand, if you're trying to say that certain users should be
given certain accesses, well, that's what the group lists are for.

I'm sure I'm missing something, and I'm really not trying to be acerbic
about it, so please accept my apology in advance if I seem to be a
smart-ass about it.  I try to keep an open mind, but if there's no One
True SuperUser on the system, having to decide who gets what access
is a royal pain.  I've had to administrate (sic) NT, and I don't like
the granularity they have there -- it's possible to completely castrate
the local administrator.

Friends don't let friends use Windows NT.
