I've decompressed the files on the CD and am making changes to them for a remastered version, not the same as a HDD install. I've chrooted into the decompressed file system and installed/removed a lot of software, and am busy making changes to the appearance of the window managers. I thought I could set the root password with the passwd command. It seems instead that doing so has not set the password, and has only succeeded in making it impossible to su knoppix.

Also, when I logout of KDE, it says "<???> logging out". I've used the login and whoami commands to make sure that I am indeed root. My passwd and sudoers files look fine to me but I'm going to try to copy the original files over them anyway when I get home tonight to see if it fixes the problem. I guess I could make a new user and remove knoppix, but somehow I think that might break a lot of the scripts that make knoppix work from a CD.
