# Launch Gerrit Code Review as a daemon process.
# To get the service to restart correctly on reboot, uncomment below (3 lines):
# ========================
# chkconfig: 3 99 99
# description: Gerrit Code Review
# processname: gerrit
# ========================
### BEGIN INIT INFO
# Provides: gerrit
# Required-Start: $named $remote_fs $syslog
# Required-Stop: $named $remote_fs $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start/stop Gerrit Code Review
# Description: Gerrit is a web based code review system, facilitating online code reviews
# for projects using the Git version control system.
### END INIT INFO
# Configuration files:
#
# /etc/default/gerritcodereview
# If it exists, sourced at the start of this script. It may perform any
# sequence of shell commands, like setting relevant environment variables.
#
# The files will be checked for existence before being sourced.
# Configuration variables. These may be set in /etc/default/gerritcodereview.
#
# GERRIT_SITE
# Path of the Gerrit site to run. $GERRIT_SITE/etc/gerrit.config
# will be used to configure the process.
#
# GERRIT_WAR
# Location of the gerrit.war download that we will execute. Defaults to
# container.war property in $GERRIT_SITE/etc/gerrit.config.
#
# NO_START
# If set to "1" disables Gerrit from starting.
#
# START_STOP_DAEMON
# If set to "0" disables using start-stop-daemon. This may need to
# be set on SuSE systems.
