Altx - Arch Live Tx - a live CD transmuter

"Arch Live Tx is a live CD developer package (not a live CD) to transmuting HD to live CD either from an exiting setup or new install. With the help of pre-installed system template (also available a set of minimum Arch Linux base packages), setup tool and simple instructions, a user can develop any type of live CD (rescue, demo, dev ) with minimum effort."
