[CentOS] Apache, SELinux, and document root on a different partition

[Kenneth Porter]

Here's what I'm seeing logged. (Newlines added to make it easier to see the 
log line boundaries with wrapping.) It looks like it's failing to traverse 
the root directory to get to the directory with the content in it, but why 
doesn't it fail on /var/www/html or home directory content, which must also 
do that?
