Thats not true, the <rel>/updates/ dir will only contain updates released from the time that the <rel>/os/ was released. However, that is not an issue since yum does not consider repositories on their own, it merges all data into one set and then selects packages to update, therefore packages from the <rel>/os/ repository get included as well.
so, you really do want to stay with the /5/ release, in order to keep getting all the latest updates etc. and not use ( as you pointed out already ) the 5.1/ or 5.0/ directories.

The problem is whether there is a way to achieve the following:
Continue to install machines with Centos 5.0(!!) distro (not 5.1, 5.2, etc snapshots|subreleases), But have .../centos/5/updates/{SRPMS|i386|x86_64}/ repositories|directories which contains updates since 5.0 to current level. This way I only need to feed yum with two repositories: centos/5.0/os/ and centos/5/updates/ -- some time will have local custom repos as well, but that is another totally different topic.
Currently I can not do it, because on Internet Centos Mirror Sites, the centos/{4,5}/updates/ are in fact symbolic links to centos/{4,5}.<latest_update_snapshot_release>/updates/ and contains update RPMS ONLY SINCE the relase date {4,5}.}.<latest_update_snapshot_release>. But what I like to have is a accumulated updates repository since {4,5}.0 release date.
I could try to emulate the effect by synchronizing each update repository for previous subreleases, For example, for Centos 4 series, sync updates RPMS for 4.0, 4.1, 4.2, 4.3, and 4.4 into one local repository and feed it to yum.conf, then sync updates for 4.5 into another repository for yum, at last, feed the repository of 4.0 base os to yum as well. Totally yum has one base os 4.0 repo, two updates repos for possible??consistent initial installation and upgrade -- If it works, then there is no need to setup new kickstart/pxe for each subrelease after the latter is released.
Has any one done the above? If so, how is that working? or there is no need to do do it because there are accumulated updates repositories on Internet Mirror Sites to sync from? Or because this is impossible because each subrelease contains new versions of packages/tools not in any updates/ repositories??
Thanks a lot.

But doesn't yum only install the newest update package anyway? You will just take up space with updates you might not need unless you need to downgrade a package, and you can't do that with yum. If I right now install CentOS 4 from the 4.0 release CD's and yum update, I will basically have the same thing as if I installed from the 4.5 CD's and ran yum update. But the updates will take considerably longer. I am having trouble grasping your dilema. The biggest difference in sub-releases are the install time tools and kernels that may have been updated when the CD/DVD's are respun.
