With Knoppix, if you really need to become root in a console all that is needed is 'su'; no password is needed.

But setting a root password IS recommended, it adds security and there are some things which will not run as nopassword root for instance 'kdesu'.

An example: If you expect to use your text editor to edit a lot of config files which must be done as root (eg perhaps you want to edit lilo.conf, fstab, XF86Config-4) to make it easier to use Kate as your editior drag'n'drop copy the 'Kate' entry from the start menu to the desktop, then change to appliction to run to 'kdesu kate' instaed of just 'kate'. This will start kate as root but you will be prompted for a password first and it will not accept a null password.

'sudo passwd root' will work to set root password but all that's required is 'sudo passwd'.
