I usually do an install into a VM from my ISO, enable the yum cache, and 
then perform an update. Once that is complete, I gzip the updates and 
get them back onto my build machine. This process is a little tedious, 
but you copy the updates into the package folder for your ISO build and 
then delete the old versions that are in there. Then just run:
rm -rf /ISO-Build-Dir/.olddata
discinfo=`head -1 /ISO-Build-Dir/.discinfo`
createrepo -u “media://$discinfo” -g repodata/comps.xml /ISO-Build-Dir
