I remastered back in 3.4 or something. And this guide:

http://www.knoppix.net/wiki/Knoppix_Remastering_Howto

Worked for me.

But when I tried it again in 4.X, it didn't go very well. Is there an updated guide I can use? A well-written one that is easy to read; not the stuff with a huge block of paragraph and the command are clearly visible from the rest of the contents.
