> Knoppix claim to fame is automatic configuration. If your Xorg or sound was giving you grief after a fresh install, you'd live boot Knoppix and copy the configuration files back to your installation.

Is it really so? I would expect all distributions to have stolen that feature by now. Xorg works out of the box basically everywhere. I've had a glitch with a microphone on a 3-pin jack on a Ubuntu system, and I doubt Knoppix would have known that a modprobe config change was needed.
