Wanting to get rid of our old Sun NIS server, but not wanting to put
a production machine totally on -current, I grabbed usr.sbin/yp* and
usr.bin/yp*, as well as include/rpcsvc/yp*.h, and built and installed
them on a 1.2-release system. Everything seems to work fine except that
when the yp master (a Sun running SunOS 4.1.3) updates a map and tries
to push it to the NetBSD machine (which is running as a slave server),
ypserv immediately dies.

Is anyone running a -current machine as a yp slave server to a SunOS
master? If so, any ideas on what else I might need to import from
-current to get this going properly?
