You can remove/replace just about anything you want using apt-get. I have installed Knoppix on several machines and I usually remove knoppix-graphics and knoppix-sounds. I stick to standard KDE graphics. I also replace the cursor (pointer) graphics using one downloaded from www.kde-look.org. You can also edit the file: /etc/motd It is the "message of the day" that says something like "Welcome to Knoppix 2.4.24" I usually change it to read "Welcome to Linux".

I also usually change sysvinit to the standard one as well. You have to be careful with that one becasue some key packages depend on it. I have written how I did it here: http://www.knoppix.net/forum/viewtop...light=sysvinit

The other packages can be removed/replaced if you want, but it doesn't hurt anything. Some are very useful, like the "netcardconfig" script which is not a part of regular Debian.
