It's so easy, you just need one command line! If there are any problems while using it - they should be solved asap if someone reports them or writes an issue about this tool.
I recommend everyone who works with servers at least once per month install jails for security reason only since everything else has been already covered. We've installed several Linux distributions but no matter what we tried out from all those solutions our main goal was always keeping control over server resources like RAM/CPU etc., which were being wasted because applications didn't take advantage enough time when needed most due some limitations within operating systems themselves.
