I think I had a count of my Knoppix Remasters at one time.

Then things get fuzzy and I wandered through the valleys of darkness for many days.

After-which... the clouds parted and the rain stopped...

An important part of the way 45xsession (which is the script that copies the files into the $HOME directory) works seems to be based on chmod g+s in the structure of any directories that need to be recursively copied. I think this is because the script runs with permissions of the staff user which is not a member of the users nor the root group.

So, when I wanted to change the default home directory... I would chmod -R 755 any directories I wanted to copy ( like .firefox ) and then chmod -R g+s those same directories.

Then in the file copy section of 45xsession I added similar lines to enrolado's script ( ie cp -R /etc/skel/.firefox $HOME 2>/dev/null ) That's about line 63 in /etc/X11/Xsession.d/45xsession
