This is what I use for DHCP/PXE kickstart files that are compatible
from FC5-F9 and RHEL4-5:

| %post --interpreter /bin/sh
| #! /bin/sh
| 
| exec > /root/post-install.log 2>&1
| set -vx
| 
| source /etc/sysconfig/network
| hostname ${HOSTNAME}
| hostname=`hostname -s`
| installdir=/srv/domain.tld/install
| installtree=$installdir/installtrees/$hostname
| logdir=$installdir/logs/${hostname}
| 
| mkdir -p /dev/shm; mount -t tmpfs none /dev/shm
| mkdir -p $installdir
| mount install.domain.tld:$installdir $installdir
| 
| mkdir -p $logdir
| if test -e $installtree/hostscript.sh ; then
|   $installtree/hostscript.sh install > $logdir/install-`date +%Y%m%d-%H%M%S`.log 2>&1 < /dev/null
| fi
| mv -f /root/anaconda-ks.cfg $logdir/
| rm -f /srv/domain.tld/install/tftpboot/pxelinux.cfg/AAAAAAAA
| 
| umount $installdir
| umount /dev/shm; rmdir /dev/shm

It's a bit obfuscated to protect the customers' data (e.g. the
domain.tld and AAAAAAAA bits). But it basically boils down to adding
as much as is needed for proper netwroking support, nfs-mounting a
central folder and calling a postinstall script there.

In this script I copy over the *.repo files I need and call yum
(actually that's a lie I'm copying channels and use smart, but it will
work with yum as well).

Using the above method gives you at the very least a cheap way to
centrally monitor your installs. There is also cobbler, a project that
does this in a more professional way: http://cobbler.et.redhat.com/
