Other than some knoppix related scripts that are installed on the machine when you do a Hard Drive install it is Debian, you have all the options that any other Debian user has.

Your better off sticking with lilo for the bootloader you have to uncomment two lines in the config file and write the changes and you have a dual boot setup.

Anybody is welcome to add the documentation at any time and I don't think you have to worry about Debian going away any time soon it is a long running project with a lot of developer support.

BTW the latest version is 2003-04-15.
