This should work.

As I understand it, as long as you have the latest packages, 
you have "5.1" or "5.2", regardless of what kickstart image 
you started with.

So, what I do is rsync (from one of the mirrors to my local 
repo) these directories:

Then, when I do a kickstart, it points to my local repo 
above. So, the instant I'm done installing a machine, it 
will always be at the latest release for all packages and 
the OS.

(And then, of course, use a cron job to continually keep the 
machine updated.)
