I have never automated my process, and I have as many versions as I want 
to blow disk space on.

For the base OS, the script that is running right now is:

# cat basesync.sh
rsync -avu rsync://mirrors.kernel.org/centos/5.4/os/i386/ \
--delete --exclude=debug/ /repos/centos/5.4/os/i386

For updates:

# cat updatesync.sh
rsync -auv rsync://mirrors.kernel.org/centos/5.4/updates/i386/ \
--delete --exclude=debug/ /repos/centos/5.4/updates/i386

'Traditionally' I run the updates script whenever I see a Centos 
Annoucement of new rpms.

I have a symlink of /repos/centos to /var/www/html so I then setup my 
/etc/yum.repos.d/CentOS-Base.repo to have:

name=CentOS-$releasever - Base

Where 5.n is the version I am running on that box. I also have a symlink 
of the current version to /repos/centos/5 so I can just use 
/centos/5/.... for the current version. I have to update that symlink 
today from 5.3 to 5.4...

Oh there is a similar line for [updates].

I recently deleted my repos for FC9 and rsynced the repos for FC11. 
There I have a bit more to exclude.

On a fresh install I boot into 'linux askmethod' off CD 1, and provide 
the URL for the base repo to install off my local repo which is faster 
than flipping through 6 CDs (and more reliable). I suspect it would even 
be faster than the 1 DVD, if I had servers here with DVD drives on them!
