when, where and how is the knoppix users set up

[mzilikazi]

Simpler solution is to find this part in '/etc/X11/Xsession.d/45xsession' script

# Copy profiles if not already present
rsync -Ha --ignore-existing /etc/skel/{file, dir, file3, ...}

and add your stuff.

Every user wiil use this settings (standard policy for '/etc/skel');

You can set stuff just for 'knoppix' user in the same script (just a few lines bellow the above example)

In that case you have to copy "your stuff" to '/usr/share/knoppix/profile'; and 'rsync' will do the rest.

Nice first post. A much better way of doing things I see.
