My goal is that any newbie who uses persistant home drive ,just has to copy the img-home-file to the root of the cd and at boot he got his own personal inviroment with his personal programs (from h-drive and so on).

This can easely be done by creating multi-session cd.

First create a smaller remastered knoppix version (with the proper changes to use the img file from the cd)

Then afterwards add the img file with multi-session.

You're right with the /home and /etc ,but using the img file your sure you got everything from your home enviroment with you and it's easier.

How to create the changes to use the img file from the cd is a lot harder I think,that's why I use the forum. 1000 brains can thin more
