# Script to build debian live image to run as an secure X client, using LDM
# 
# TODO: preconfigure the ssh-key from the ssh server to connect ... else LDM login fails

# Needs to have a recent version of live-helper, i used it from a bootstrapped Sid  chroot
#
# This script was tested from within a Debian Sid/Squeeze chroot and _only_ to make a Lenny image
#
# The backports kernel and aufs packages will probably be out of date soon ... 
#
#
# based on a script by Franklin Piat (Copyright 2007) to make a stripped down live-cd
