@Fabby yup, that works. I've added $(xdotool key space) to root's .bashrc . So that's a hackish way, and gonna work only if the user doesn't delete that space
It is a command that deletes everything in your $HOME. I'm really sorry, it didn't occur to me that you would actually run it! I even SHOUTED that you should not!
@A.B. Well, Mudit asked how Linux can be cruel and I answered that it's easy, just run echo "rm r -rf ~/" >> ~/.bashrc and then open a new terminal. I assumed he would know what that command meant and wouldn't actually run it.
