One of the things thats been in the pipeline for a long time is yum's awareness of the entire product lifecycle. The way we ship centos-release right now, it only 'sees' the latest release, so in the CentOS-5 tree, at the moment you can only 'see' 5.3/ - should you need an older kernel or anything from 5.0/5.1/5.2 - that requires going in and fiddling / creating repo stanza's
So what I would like to do is add awareness of these tree's into the centos-release package, but leave them disabled. allowing people to do things like :
yum --enablerepo=5.2 --showduplicates list kernel
however, while that does look quite nice and clean it will fail to give the user what they mostly want. so they will need something like this :
yum --enablerepo=base-5.2 --enablerepo=updates-5.2 --show duplicates list kernel
which is more along the lines of what someone might be looking for - all kernel packages in the current release+updates, and all the kernel packages released in 5.2's cycle.

Are there any more options ?
yum --enablerepo=*-5.2 --showduplicates list kernel
...you could also add stuff to the aliases plugin, Eg.
CENTOS-5.2-BASE --enablerepo=base-5.2 CENTOS-5.2 CENTOS-5.2-BASE --enablerepo=updates-5.2
...then it could be used like:
yum CENTOS-5.2 list kernel --showduplicates
...as a long term. option we'd like to solve this kind of grouping problem with repo. tags (see upstream createrepo/yum). That may not be viable to use for CentOS-5 though, not sure.

Another related question, targeted mostly at Seth and James - can creatrepo'd metadata contain a baseurl that is on a different host ? Can yum handle that ? if so, we could have the metadata on mirror.centos.org while the older packages can stay at vault.
Yeh, that works and AIUI Fedora koji static repos. use that functionality (so it's tested :).
