As Stephen says, use cobbler (we do as well!) and put it into your
kickstart.
Here's ours:
================== sample.ks =================

# System bootloader configuration

# Firewall configuration - switch this off as we will apply it using
# puppet
firewall --disabled
# Run the Setup Agent on first boot
firstboot --disable
# System keyboard

# System language

# Use network installation

# If any cobbler repo definitions were referenced in the kickstart
# profile, include them here.

# Network information

# Reboot after installation

# System timezone

# Install OS instead of upgrade

# Clear the Master Boot Record

# Start final steps

# End final steps
========== END Sample.ks =================
All the $SNIPPET stuff is cobbler specific, but the Puppet config stuff
should work as part of any kickstart.
HTH,
Matt.
