Jose,

Stop and think about it - do you really want any user to be able to switch run levels? I don't think so.

You could look into sudo:

You can't.

init is always running (check out "ps -fp1").

When you run init from the command line you send a signal to the real init, and if you aren't root, you don't have permission to send the signal.

It would be extremely scary to think it could be otherwise. If any user could run "init 2", to bring he system down to level 2, there would be mayhem.

You really don't want your users sending random signals to "init". If you want to achieve it yourself you can write a quick "C" wrapper around the command which you then set as SETUID or you use an application like "sudo" which you can get from here
