DebianLive

"This is a collaborative wiki to gather information and to discuss technologies to be used to produce a complex framework to enable production of official Debian Live systems, that uses as much as possible official Debian packages and, for optional hard disk installation, the Debian Installer.

A Debian Live system is a [WWW] Debian operating system preinstalled in some way, that does not require a classical installer to be used. It comes on media, like a cdrom, a usb-stick, or over a network."
