I'm trying to set up a specific directory structure for each home folder whenever I add a new user. I have what I want in /etc/skel, but I'd also like to eliminate the Documents, Music, Pictures, etc. folders that Ubuntu automatically creates when a new user is added. Is there any way to do this? Where are these extra directories defined? I didn't see anything in the /etc/adduser.conf file--is there some additional script that is run whenever a new user is added?
