# NAME
# ypmake - NIS master script to update databases and to rotate logfiles
# SYNOPSIS
# /var/yp/ypmake
# DESCRIPTION
# ypmake is run on NIS master servers by cron(1M) to ensure that their
# NIS databases are up-to-date and pushed out to slave servers.
#
# You can also use this script to push a map after updating its
# data file. Any output from the make is printed on the standard output.
#
# An optional configuration file, /etc/config/ypmaster.options,
# lets you customize the variables used by make when it creates
# the NIS databases. See ypmake(1) for details.

# Make sure another ypmake isn't running already. Do an echo after fuser output
# because sed doesn't always work correctly without a newline
