Yeah. Postfix is chrooted -- it asks me fairly frequently to copy files
from /etc to where it lives...

I was just hoping to find a bind config mentioning the file in /etc.

It isn't, but a folder and a file got installed in /etc somehow.

I try to keep an eye on them to see if they get out of sync.

Yes. There's a dedicated NTP server on the DMZ to sync all the clocks
in my nets. (I live in Boulder County, USA, so NIST is just down the
street -- I have a 10 or 20 ms latency to their atomic clocks.)

Since I've never seen AA, I don't know for sure what an AA profile looks
like, but I have reason to believe this is one...

It doesn't exist, and it's not running. But the named profile exists...

Any idea how to do that? From what I've found, AA does look like it might
do me some good. But it's (allegedly) not here yet.

I'd have thought so too, except that it appeared in /etc somehow and seems
to affect bind9.

root# locate apparmor
-bash: locate: command not found
I've done whereis and which. Both say AA isn't there. And ps says it
Aptitude doesn't find locate either. Is it part of some package?
