This is excellent news. After the long lead times for 6.0 and 6.1 its very reassuring that CentOS seems to have gotten its momentum back and is tracking the Red Hat releases with minimal lag.
When did they start doing that? The last time I tried to find a window into the CentOS process, the Powers That Be were ignoring or belittling anyone who wondered what was going on or how to help.
The mailing lists are where it was happening early this year. Look through posts from Karanbir Singh, it was like pulling teeth just to get him to tell people how they could help with testing (knowledge previously limited to some semi-private group nobody knew how to get involved with).
Definitely didn't want to talk about build processes, just lots of handwaving about how hard it is to get right. I even recall he eventually pointed out some "build scripts" under pressure, neglecting to mention that they weren't actually usable by anyone without hidden knowledge and package requirements he didn't want to talk about.
The whole thing left a very bad taste in my mouth.
I did a Google search and apparently the bug is fixed in later versions of Fedora, so it's just a temporary situation with RHEL/CentOS I'm assuming.
I think the easiest way to check if your server would be affected is to boot from the CentOS 6.2 netinstall CD, and see if it can access the network. If that works fine, everything should be good.
