unfortunatly , some user never use a terminal and would'nt know how to use a command line as "sudo su /sbin/reboot" the purpose here was to enable restart from the drop down menu withing the gnome session .
Actually command lines are specified in menu items and icons...
I don't think sudo works from a menu, you need gksudo or ksudo for that. That said, sudo is a hammer compared to polkit. For example, polkit can restrict allowed actions to a user present at the physical terminal (as the OP wanted), I don't think sudo can do that.
PS: I use sudo all the time, but then on my machines, I'm the only real user.
