What we need is a "What would a good sysadmin think?" list where one of the criteria for being a good sysadmin would obviously be that you know something about Centos but the rest of the scope covers applications, conversions, product comparisons, legal issues, etc. The kind of stuff most of us do every day...
Hmm... I had been contemplating a generic linux-sysadmin or linux-systems list for quite a while. My vision for the list would be OS distribution neutral, though. Some of us do work in multi-OS shops, afterall. If there is enough interest (reply to me privately, please) I can set something up.
Otherwise a centos-sysadmin list is a good idea, I think.
