dr_azeem,
no need for hdinstall

if you read http://www.knoppix.net/docs/index.ph...masteringHowto
and have about 5/10 gb HD it's fairly easy to remaster the cd to add whatever you'd like.
even the knoppix novices have had sucess remastering the cd. I myself being one of them. but most novices, like myself, remaster the cd for our own needs. While some of the advance users remaster because they have difference ideas which packages should be installed or what wm (window manager to use)

to see if any of them fit your needs, there are alot to choose from
