In my line of work I've had to come to some measure of acceptance of 
SELinux, and I think once people get the hang of its principles and 
premises they'll be less inclined to simply disable it to get their stuff 
to work. Not that I blame them at all - that's what I did for years.

For example, with a bit of patience and perseverance I was able to find 
out that you can get Ganglia-Web to work by adding TCP port 8652 to the 
http_port_t port list which limits the list of ports to which the web 
server is allowed to initiate connections, and this capability is quite 
appealing to me as I'm recalling some of the interesting times since that 
fateful post in alt.hypertext in 1991. :-D

I'm not sure when I'll be able to patch systemd on the machine, but 
hopefully that'll eliminate the error message.
