Well, I know I have benefited from the discussion because I understand the challenges that face the CentOS team with regards to security updates whilst they are rebuilding a point release. As has been pointed out to me, we're between a rock and a hard-place and it isn't just a simple matter of not enough resourcing - which is what I thought the issue was... now I stand corrected. Obviously, the security concern is not unreasonable because the CentOS team are considering a different approach for 5.4. What I also now know is this is inherent in any rebuild, so I know have to consider whether a rebuild is the best approach for me.

So, for those of you who consider this as "in-fighting", know that some considers it "learning".
