You aren't getting my point. I want a way to be full root in Knoppix while in the rescue mode, not running in root all the time.

Of course we have to learn Linux but we need powerful tools once in a while to extract ourselves from very deep holes that we can fall into. I want a tool that will let me into any file of another fubar linux installation on my computer to get it back in working order rather than blow it away and reinstall.

I suppose in the wrong hands that could be dagerous as they could blow past security on other people's machines by simply rebooting the computer with a Knoppix CD and then becoming root.
