[Users] Combine Fedora and EL6

[Jonas Israelsson]

Greetings.

Just have to ask... While having issues installing a node based on el6 I
instead tried one based on Fedora (Same version)
This seem to work just fine. I now see some other issues that I believe
are unrelated still just to double check.

Is it "supported" mixing nodes based on FC19 with an engine running EL6
and vice versa as long as the versions are the "same" ?
