Neither am I. That's why I look at the logs when something goes boom so 
that I can have it taken care of.

Let me just say that the pointers I received and implemented have not 
given me any trouble even though the Moodle box I received from HQ has 
the mysql db in a non-default location and likewise the content.

I, thus, find it rather irksome when people pop up here and say SELinux 
is a troublesome piece of rubbish that cannot be trusted but in reality 
they have not got a good enough understanding of the works (and in some 
cases don't even try to) and so things fell apart. I did not understand 
SELinux at first either when it first come out but it took just one 
morning when I really had to get it working. In case I come across as 
some pompous arrogant ass, let me just say that I only got SELinux 
running on a Centos box very recently (Sep 2010) and so others are more 
qualified to advocate SELinux but it sure was NOT rocket science to make 
sure Moodle and Mysql in areas outside /var/lib/mysql and /var/www/html 
still worked.
