And I forgot to mention also, that I have to use a custom script to 
rewrite the IP in the boot.log, otherwise at the end of the 
installation, fai-chboot fails to connect to the server and change the 
pxelinux.cfg file to foo.disable.  Here is that script:

#! /bin/bash

error=0 ; trap "error=$((error|1))" ERR

set -x

REALIP=$(echo `host $(cat $target/etc/hostname) | awk '{print $4}'`)
perl -i -pe "s/^IPADDR=all(.*)/IPADDR='"$REALIP"'$3/" $LOGDIR/boot.log

exit $error

HTH,
