Also, I much prefer their packaging of Apache & BIND9 to Red Hat's. I personally love their minimal installation CD, from the text based install to the minimal package install, etc. and think that their minimal approach is vastly superior to Red Hat (and all downstream packagers) installer that is slow and bloated. I can typically get a vm spun up with Ubuntu in about 5 mins and it takes much longer to install a CentOS vm. If your expectation was that you could take your limited knowledge base and apply it equally across all Linux distributions and expect it to behave as a Red Hat derived system, then all other distributions will disappoint you.
