Can I give certain applications their own rights, e.g. passwords, different from root password?
The reason I want to do this is, apps like compiz, settings manager, that don't need root access. This creates a problem when I show others Ubuntu or let them use it. They may think playing something like this is fine, as it looks like it just changes some effect but the reality is it could break Ubuntu if misused.
I would like others to just use my profile but apps like this make it a risk.
So is this possible?
