# 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.
