To the comments in the posting re: CentOS release cycle. Might I suggest looking at Scientific Linux (SL) <a href="http://www.scientificlinux.org/" rel="nofollow">http://www.scientificlinux.org/</a>. This is also a derivative of RHEL sponsored by Fermilab & CERN for the scientific community.
Despite this being about RHEL, everyone is talking about CentOS. From what I've followed on the mailing list it seems as though they're focusing more on deploying a better QA toolkit which will speed up releases. If that's the case then it may be wise to continue waiting on CentOS to get its act together. But, then again, I could be misreading.
The comments here do not seem too promising for CentOS. Too bad...<p>Whats the replacement then? Debian and FreeBSD spring to mind, but both are rather different beasts.
