Is there a way to prevent, intercept , or password protect a run level change. For example if some types init 6, or reboot from root, I would like to be able to have more control of that. Looking for idea besides controlling root login access itself. Thanks

Root is omniscient.

I don't think it *is* possible. If someone 'roots' you, well - then they got the ball.

Anyone else?

As far as I know (however much that is ), you can't set permissions for root, you need him to have permission. Sorry...

You could try changing inittab and forcing it to execute a program of yours if you 'd like but as long as someone has your root password, or just happens to have root access in some way, I believe he would easily find out what to do after some trying. The truth is, as already told by the previous guys, when someone has root access to your linux box that souldn't have... you are in big trouble! ;-)

PS. Kids don't try this at home! ;-) You could end up with a destroyed linux system... You may even not be able to boot your linux box! I warned ya...
