# Provides: core-daemon
# Required-Start: $network $remote_fs
# Required-Stop: $network $remote_fs
# Default-Start: 3 5
# Default-Stop: 0 1 2 6
# Short-Description: core-daemon
# Description: Start core-daemon
# continued on second line by '#<TAB>'
# should contain enough info for the runlevel editor
# to give admin some idea what this service does and
# what it's needed for ...
# (The Short-Description should already be a good hint.)
### 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!)

# 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
