To install the Ubuntu-Rescue-Remix on a regular Ubuntu install (hardy) add this to your sources.list

deb http://ppa.launchpad.net/arzajac/ubuntu hardy main
deb-src http://ppa.launchpad.net/arzajac/ubuntu hardy main

and then run

sudo apt-get install ubuntu-rescue-remix

This is not ready for general use. I plan on separating the package into two smaller metapackages: ubuntu-rescue-remix-live and ubuntu-rescue-remix-tools. There is no need to install the live cd components on a regular Ubuntu install that already boots from a hard drive and uses a volume-manager to mount removable devices.
