Anaconda seems to exclusively build off of the hdlist, so you would have
to rebuild it if you want to come out of the anaconda install with a
fully patched system. I do this for Centos4 with no major problems. If
you like, I can send you the commands that you need to run to do this.
I actually keep a full package respository locally for Centos, and
nightly pull down all the updates, and rebuild the hdlist, and yum
headers. When I build servers, I use kickstart off of my own
repository. 0 -> fully patched centos4 server in 5 - 10 minutes,
depending on what is installed =). I then keep servers updated with
yum, off of the same repository.

If you use kickstart, you can always add a yum -y update in the %post
section. You'd still have to download 200MB of data, but at least it
would be part of the build.
