# run this script to create a LiveCD in /tmp/livecd.iso
# Your kernel image has to be in $ROOT/boot/vmlinuz or $ROOT/vmlinuz
# 
# Urs Beyerle:
# - add x86_64 support
# - add support to build for UP and SMP kernel
#   SMP kernel is added to LiveCD, if variable $SMP is set
# - copy /boot/System.map-* and /boot/config-* to $CDDATA/boot
#   copy /boot/grub/splash.xpm.gz to $CDDATA/boot/grub
#   copy /boot/message* $CDDATA/boot/
#   copy /boot/symvers-* $CDDATA/boot/
#   all needed for install LiveCD in local harddisk
# - config no longer sourced, we take ../livecd.conf
