+# LSB compatible service control script; see http://www.linuxbase.org/spec/

+# Note: This script uses functions rc_XXX defined in /etc/rc.status on
+# UnitedLinux/SUSE/Novell based Linux distributions. If you want to base your
+# script on this script and ensure that it works on non UL based LSB
+# compliant Linux distributions, you either have to provide the rc.status
+# functions from UL or change the script to work without them.
+# Honestly, you'd be better off basing yours on the skeleton template.
+# See skeleton.compat for a template that works with other distros as well.

+### BEGIN INIT INFO
+# Provides:          solr
+# Required-Start:    $local_fs $remote_fs
+# Should-Start:      $network $time
+# Required-Stop:     $local_fs $remote_fs
+# Should-Stop:       
+# Default-Start:     3 5
+# Default-Stop:      0 1 2 6
+# Short-Description: Solr daemon providing search services to eZ Find
+# Description:       Start Solr to provide search services for eZ Find.
+#	Solr is the backend indexer and search service used by eZ Find,
+#	which provides the search results on the eZ Publish site.
+### END INIT INFO
+#
+# Any extensions to the keywords given above should be preceeded by
+# X-VendorTag- (X-UnitedLinux- X-SuSE- for us) according to LSB.
+#
+# Notes on Required-Start/Should-Start:
+# * There are two different issues that are solved by Required-Start
+#    and Should-Start
+# (a) Hard dependencies: This is used by the runlevel editor to determine
+#     which services absolutely need to be started to make the start of
+#     this service make sense. Example: nfsserver should have
+#     Required-Start: $portmap
+#     Also, required services are started before the dependent ones.
+#     The runlevel editor will warn about such missing hard dependencies
+#     and suggest enabling. During system startup, you may expect an error,
+#     if the dependency is not fulfilled.
+# (b) Specifying the init script ordering, not real (hard) dependencies.
+#     This is needed by insserv to determine which service should be
+#     started first (and at a later stage what services can be started
+#     in parallel). The tag Should-Start: is used for this.
+#     It tells, that if a service is available, it should be started
+#     before. If not, never mind.
+# * When specifying hard dependencies or ordering requirements, you can
+#   use names of services (contents of their Provides: section)
+#   or pseudo names starting with a $. The following ones are available
+#   according to LSB (1.1):
+#	$local_fs		all local file systems are mounted
+#				(most services should need this!)
+#	$remote_fs		all remote file systems are mounted
+#				(note that /usr may be remote, so
+#				 many services should Require this!)
+#	$syslog			system logging facility up
+#	$network		low level networking (eth card, ...)
+#	$named			hostname resolution available
+#	$netdaemons		all network daemons are running
+#   The $netdaemons pseudo service has been removed in LSB 1.2.
+#   For now, we still offer it for backward compatibility.
+#   These are new (LSB 1.2):
+#	$time			the system time has been set correctly
+#	$portmap		SunRPC portmapping service available
+#   UnitedLinux extensions:
+#	$ALL			indicates that a script should be inserted
+#				at the end
+# * The services specified in the stop tags
+#   (Required-Stop/Should-Stop)
+#   specify which services need to be still running when this service
+#   is shut down. Often the entries there are just copies or a subset
+#   from the respective start tag.
+# * Should-Start/Stop are now part of LSB as of 2.0,
+#   formerly SUSE/Unitedlinux used X-UnitedLinux-Should-Start/-Stop.
+#   insserv does support both variants.
+# * X-UnitedLinux-Default-Enabled: yes/no is used at installation time
+#   (%fillup_and_insserv macro in %post of many RPMs) to specify whether
+#   a startup script should default to be enabled after installation.
+#   It's not used by insserv.
+#
+# Note on runlevels:
+# 0 - halt/poweroff 			6 - reboot
+# 1 - single user			2 - multiuser without network exported
+# 3 - multiuser w/ network (text mode)  5 - multiuser w/ network and X11 (xdm)
+#
+# Note on script names:
+# http://www.linuxbase.org/spec/refspecs/LSB_1.3.0/gLSB/gLSB/scrptnames.html
+# A registry has been set up to manage the init script namespace.
+# http://www.lanana.org/
+# Please use the names already registered or register one or use a
+# vendor prefix.
