Either that or a separate "practices" list. This discussion was _definitely_ a candidate.
A large majority of the discussions that, while useful, tend to get a little pedantic, would be good candidates for a list such as the one you describe above. I'm not sure it needs to be CentOS specific. Maybe it does. I don't know. It's a good idea, though.
I know that there have been many times where I've asked a question on a list, be it a Java list or a distro list such as SuSE or CentOS, where the question wasn't a "How do you do X in CentOS?" question as much as it was "What is the best way to accomplish X with Linux?" question.
It's an idea with merit. A list where the best practices for how to get something done (especially since many here are using CentOS as an enterprise OS) would make sense in that context. It would definitely cut traffic here down to basic questions about the distribution.
