more /usr/sbin/ypinit
...
for host in ${HOST_LIST};
do
        echo "${host} ${host}" >> ${YP_DIR}/ypservers
        echo "${host} ${host}"
done | ${MAKEDBM} - ${YP_DIR}/${DOMAIN}/ypservers

This makes /var/yp/ypservers like this

my_host_name     my_host_name
slave1_name    slave1_name
slave2_name    slave2_name

When type make under /var/yp, it complains:

yppush: transfer of map passwd.byuid to server slave1_name slave1_name
slave1_name failed
yppush: status returned by ypxfr: no such host
yppush: transfer of map passwd.byuid to server my_host_name failed
yppush: status returned by ypxfr: Master's version not newer
Pushed passwd.byuid map.
Updating netid.byname...
yppush: slave1_name slave1_name slave1_name : couldn't create udp handle to NIS
server: RPC: Unknown host

When changed it to following format, "make" is happy (no master name --
my_host_name):
slave1_name
slave2_name

So, question is that does ypservers do require  master_name in ypservers?
My guess is not.
The double-entry is not needed because it do nothing good.

If both are true, we need to make quick fix in ypinit script in all new
releases.
