I checked and I DO have the @core group installing with the kickstart.  
  Where can I find more about package ordering?

Also, I'm not sure if this is pertinent or the venue for this or not  
but I'm creating a new ISO image of the DVD.  I'm adding the repo*.rpm  
to the list of rpms already on the DVD and running createrepo which  
takes quite a bit of time.  Then I create a new ISO image and use it  
to install.  Is there a way of just adding a separate directory to the  
ISO image and somehow telling anaconda about the directory?  That way  
I only need to do the createrepo command on the smaller directory.  I  
guess my question is, "How does anaconda know where to look for rpms?   
BTW Its RHEL 5.3.
