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. Of course this means you have to go to the console each time you want to boot, and you won't get reboots on failures/etc. rod ______________________________ Reply Separator _________________________________ Subject: Re: snooper watchers Author: Karl Strickland <karl@bagpuss.demon.co.uk> at Internet Date: 2/28/95 10:50 PM whats this mean is someone saying rm'ing /dev/nit and hacking mknod out of the kernel is better than just taking nit out of the kernel?
