I'm Afraid Of The Power, What Is It Like Being In Control?

Okay, imagine this scenario. Rambo, First Blood Part 1. Rambo decides instead of being powerful and running as root, he'll run as the user account john. So he caused a bit of a ruckus in the town, and Colonel Trautman, who is running as root, contacts Rambo over the radio. He tells the lowly user john to come back to base and surrender himself. In this version, Rambo turns himself in, instead of getting to shoot that sherrif a couple times.

That's probably the worst movie ever. Do you know why Rambo is awesome? Because he ran as root. He told the Colonel that he would be making his own decision that day, and I think we can all agree it was the right one.

Do you know why Colonel Trautman couldn't save Rambo with the helicopter in First Blood Part 2?

For some reason, he thought it would be a good idea to start running in a user account. Too bad Murdock ran as root. That's why Rambo had to run as root, otherwise the command

killall commies

would get him a permission denied error. There was no time to ask Murdock for kill rights and frankly, he wasn't going to grant them.
