Tails (The Amnesic Incognito Live System) http://en.wikipedia.org/wiki/The_Amnesic_Incognito_Live_Syst..., a Debian fork which forces Tor for all outgoing and incoming connections. Designed to be run from read-only media.
"For various reasons Tails tries to diverge by the smallest possible amount from its upstream projects, and especially from Debian"
"We try to push our changes upstream when we need to modify software we ship. This often requires us to write code in a generic way, rather than implementing ad-hoc hacks to fit our specific needs: e.g. we often need to make the stuff we need opt-in and add configuration options."
The official term for this is "Debian derivative" rather than "fork."
Or is this proof of tor being better than nothing?
