Skolelinux Live provides a simply way to demonstrate Skolelinux possibilities for end users. It has been built over the Skolelinux "standalone" installation. It does not need to be installed on a hard drive, but you can do that using Live Installer. The iso image features many additional wireless devices drivers (wifi) to make it more useable. It's an unofficial release not provided by Skolelinux team.
