I jsut got Fedora Core test2 and upgraded to 2.6.4 kernel, I will run it for a while, if you are planning on web hosting, and nothing related to performance hungry game servers, use BSD! far the best. stick with 4.9.
If you want to run game servers, i've found a lot of performance tweaks and have had a custom OS image made for me. Fedora far over-rates anything non-windows in game server performance.
Well it's not quite the same when you have many servers already running. It's easily said than then to change the whole base OS. Now if it is just a home server or just a single server, obviously it's not an issue.
Progeny charges the same as Redhat used to, so going with them is fine. But they don't do bug fixes. So any bugs will be there forever.
Dynamicnet, how do you manage with both Progeny and Fedora-legacy? Would the packages interfere with each other?
