What is an easy way to remove all packages at once. I just need the ones I want installed. No Accessories, Education, Games, Graphics, Internet, Office, Programming, Sound, ect. I only want Konqueror and rdesktop? I am remastering a dvd and I want my Knoppix build to only have these. I want it as lightweight as possible. I want this for a student lab environment. Thanks greatly for all input.
