[cobbler] Installing new OS against new Packages

I have a cronjob that downloads the latest packages from Oracle's repository once a week. This local repository is not handled by Cobbler but one could essentially run "yum update" against it. How can I set up Cobbler to install new machines and pull down these latest packages instead of the DVD tree? One option is to install against the DVD tree and then run yum update, but I'd rather kill two birds with one stone. -- Sam Sen Sr Systems Administrator 215.913.4797 Aria Systems, Inc. 600 Reed Road, Suite 302 Broomall, PA 19008 www.ariasystems.com<http://www.ariasystems.com/>
