The SELinux list would be where you would find the SELinux 'guys' so that
would be, IMO, a better place to look for SELinux help than here on a
general list. If I was having a problem with some application, pick one, I
would go to its support list.

In Fedora 7 was the beginning of a trouble shooting GUI for SELinux. In
Fedora 8 it is now working quite well. When SELinux 'sees' what it
'Thinks' is a 'bad thing trying to happen' it will tell you with an applet
warning in the task bar. Clicking on the applet brings down a window with
a pretty complete explanation of what is happening, what it thinks is
wrong and why. If you disagree just keep reading the very short paragraph
and it will tell you how to change the setting. Verbatim. If, it happens
very seldom for me, the setting can not be changed it will offer you a bug
report.

Fedora Core 6 is EOL in December. I would consider that 'older'.  ;-)

BTW Happy birthday. You got me by a little more that 12 years.

That sounds interesting. I was never much good at cabinet/finish work in
wood. Framing is about my limit there. My trade is sheet metal. HVAC That
I can do from flat sheets to the 'last screw'.  ;-)

This is getting OT for this list.
