# This script is part of ypserv package.
# We need to pass all environment variables set in /etc/sysconfig/yppasswdd
# to rpc.yppasswdd daemon, but only if they are not empty. However, this
# simple logic is not supported by systemd.
# This script wraps the main binary, prepares YPPASSWDD_ARGS variable
# to include all necessary variables (ETCDIR, PASSWDFILE and SHADOWFILE)
# and passes this variable to daemon.
# The script ensures, that the rpc.yppasswdd arguments are not used in case
# the appropriate environment variables are empty.
