I'm configuring Ubuntu 12.04 for my sister. I'd like to give her a system that she really can't screw up, but can still do normal things like install software.
I don't want to just add her user to
/etc/sudoers so that she can become root because she could possibly mess something up.
I know that I should be able to get around this by just adding her to the necessary groups, but I'm not sure which ones those should be.
Could anyone suggest them or point me in the direction of some kind of list that heavily used software in Ubuntu requires group membership?
