Hi,

this is done with a hook ...

http://fai-project.org/fai-guide/ar01s07.html#_anchor_id_hooks_xreflabel_hooks_hooks

the recipe can probably be found somewhere on fai-project.org but here's an example:

tutor:/export/home/fai/config# cat hooks/chboot.DEFAULT 
#! /bin/bash 
# hook for fai. Set boot to local 
set -xv

SCRIPTNAME=`basename $0`
skiptask=`echo $SCRIPTNAME | sed "s/\..*$//"`

cd /tmp 
TFTPCONFDIR="/boot/fai/pxelinux.cfg"
SSHUSER=fai
TFTPSERVER=$installserver

HOSTNAME="local"

BOOTIP=`ifconfig "$netdevices_up" | grep 'inet addr:' | sed "s/[^:]*://" | cut -d " " -f1 | sed "s/\./ /g"`
BOOTIP=`printf "%02X%02X%02X%02X\n" $BOOTIP`

echo Next Boot will boot or install: $HOSTNAME on $BOOTIP.

case $HOSTNAME in
      local)
          ssh -o StrictHostKeyChecking=no $SSHUSER@$TFTPSERVER "mv $TFTPCONFDIR/$BOOTIP $TFTPCONFDIR/$BOOTIP\.disable ; \cp $TFTPCONFDIR/local $TFTPCONFDIR/$BOOTIP " ;;
      *)
           ssh $SSHUSER@$TFTPSERVER "\cp $TFTPCONFDIR/$HOSTNAME $TFTPCONFDIR/$BOOTIP" ;;
esac

skiptask $skiptask

# End of hook chboot.DEFAULT
