Give him the Terminal and NetInfo Manager to play with, I'm quite sure the putz can find enough parameters to screw up that he'll need to reinstall the OS.
The OS has diverged some from the NeXT OS that it used to be, but the old Mac OS is a fancy GUI, and you can't mess with it doesn't hold water anymore -- if you want the play with it, you can.
Just takes some hunting to find out wher the stuff is stored so this putz can render the OS non-functional, and/or delving into the developer toolkits.
