Brian, I would invite you to go back and look at who you were
"debating" (if you can call it that). Other than my original
analogy versus the firewall (after you brought up the concept
of a firewall), others have been "debating" you.
You owe me _no_ explaination. I just don't agree with your
assertion that SELinux is "broken." I've tried to point out
that under your same definition, a deny all outgoing policy
default on a firewall would also be considered "broken."

People who use Windows have problems when Windows 2000 Server
with Service Pack 3 is configured to CC EAL-3 standard as
well. It's all about what security level is usable. SELinux
is only going to raise the CC EAL certification of Linux,
which some customers _do_ consider as important.
And it's _always_ going to break things as a result. Just as
RBAC/MAC does in Windows when it's enabled -- only far worse
(because nearly all Windows programs are RBAC/MAC ignorant).

Then that's a problem outside the scope of this discussion.

And I'm _not_ the one that says you can't switch it off. I
had a problem with you saying it is A) "broken" and B)
"firewalls" just work. Once you started ""debating others, I
kinda just left it for awhile.

This "bully boss attribute" is a "necessarily evil" in the
future of Linux. RBAC/MAC isn't going away. And it's not

RBAC/MAC will _always_ cause headaches.

RBAC/MAC enforcement isn't history. It's the future. Get
used to it because you're going to be seeing a lot more of
If you don't want to deal with it now, fine. I never said
you had to. I just said that it's not "broken" -- it's a
kernel enforcement that you will run more and more into in

"Improvements" are subjective. But most agree that RBAC/MAC
is one of the most important "improvements" in the future of
Linux. And there is a very good chance it will become
defacto standard in Linux, because applications can be made
to work with it.
Unlike 99.9% of Windows software with NT's RBAC/MAC (at least
through version NT 5.1).

It's a debate you're having with others than myself. But you
can continue to respond to my posts as if I made the
statements if you wish.
