install live-helper, I suggest using the latest version from the live-helper repo - deb http://live.debian.net/debian/ ./
I made a folder to work in
mkdir work
changed to that folder
cd work
changed to root
su
told live-helper what I wanted to do
lh_config --bootstrap copy --debian-installer live
told live-helper to build the ISO
lh_build
when it is done binary.iso is the finished iso
and that was that....
