[CentOS] Kickstart with all the latest updates?

Currently, I kickstart my machines over http to install CentOS 4.4  
and then in a script called from %post do a "yum -y update" to  
install all the latest updates.  Is there a way to set up the  
kickstart server so that I can do this all in one step?  In other  
words, is there a "supported" way to roll in all the updates into the  
kickstart server?  In case it matters, I set up the kickstart server  
by copying the contents of all CentOS 4.4 CDs (well, from the ISO  
images actually) into one directory, and then configuring the  
kickstart file to point to that URL (via http).

Thanks,
Alfred
