An UNOFFICIAL response....

If I ever need to disable NIS on a machine because no servers are
around, I push the big yellow switch (unless the system gives me
a chance to type "shutdown -Fr"), wait for the message
"Starting tcpip daemons" to come up on the screen, and then
immediately press control-C several times.  This seems to abort
the boot sequence early enough that ypbind doesn't start.

Then I edit /etc/rc.nfs and comment out the line that starts ypbind
and "shutdown -Fr" to boot the system properly.
