     The best thing to do is take the nit support out of the kernel and 
     remove /dev/nit.  Now someone would have to build a new kernel and 
     reboot the machine to replace the nit support.
     
     If you are overly concerned about this, you can set the boot device 
     (in the rom monitor on a sparc) to boot off of some other disk, one 
     that is not bootable or not there.  Then a reboot/fastboot/shutdown 
     -r/etc will not be able to automatically bring the system up.  I don't 
     believe that you can specify boot devices from a unix reboot type 
     command.

is it not possible for a hacker to set his own boot device before performing his
reboot, and then reset it back to whatever-it-was later?  ie by messing with
/dev/openprom or whatever its called
