### BEGIN INIT INFO
# Provides: skeleton
# Required-Start: $local_fs
# Should-Start:
# Required-Stop: $local_fs
# Should-Stop:
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Example initscript
# Description: This file should be used to construct scripts to be
# placed in /etc/init.d
### END INIT INFO
# The definition of actions: (From LSB 3.1.0)
# start start the service
# stop stop the service
# restart stop and restart the service if the service is already running,
# otherwise start the service
# try-restart restart the service if the service is already running
# reload cause the configuration of the service to be reloaded without
# actually stopping and restarting the service
# force-reload cause the configuration to be reloaded if the service supports
# this, otherwise restart the service if it is running
# status print the current status of the service
# The start, stop, restart, force-reload, and status actions shall be supported
# by all init scripts; the reload and the try-restart actions are optional
# Common steps to convert this skeleton into a real init script
# 1) cp skeleton <the_real_name>
# 2) Set DESC and NAME
# 3) Check whether the daemon app is /usr/sbin/$NAME, if not, set it.
# 4) Set DAEMON_ARGS if there is any
# 5) Remove the useless code
# NOTE: The skeleton doesn't support the daemon which is a script unless the
# pidof supports "-x" option, please see more comments for pidofproc ()
# in /etc/init.d/functions
# PATH should only include /usr/* if it runs after the mountnfs.sh script
PATH=/sbin:/usr/sbin:/bin:/usr/bin
