Hi, I've downloaded Knoppix 3.2 (2003-06-06) and think it's great. But
I want to change a couple of things in the ISO before burning it on
CD. Say, make "knoppix lang=en" the default, or add "export LESS=-F"
to /etc/profile. How would I go about it?

P.S.: I'm learning Linux, but am not very experienced.

Many thanks.
