Since the "SELinux - way of the future or good idea but !!!" thread is deep in heated discussion, I decided not to derail to ask a simple question.

I found this guide for SELinux: http://www.linux-books.us/centos_0005.php  and it looks like it's straight out of RedHat.
However, it's dated 2005.  Will this be sufficient to help understand a CentOS 5 - or 6 - installation of SELinux?
Is there a more recent guide (freely) available out there?

Thanks in advance,
Rob
