What I've done is copy the pxe-boot files (in the /images/pxeboot/ dir
on CD1) to /boot/ and add them to /etc/grub.conf and set it as the
default. The server will then boot off the installer kernel & initrd...


In theory, I have not tested this part, the kickstart upgrade process
will install a new kernel and set that to be the default. So when the
box reboots, you can log back in and remove the installer kernel from
/etc/grub.conf.

All of this is "non-trivial", but should be easy to replicate once you
understand how all of the pieces fit together.
