# Template system startup script for some example service/daemon NRPE
#
# LSB compatible service control script; see http://www.linuxbase.org/spec/
#
# Note: This template 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 template 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.
# See skeleton.compat for a template that works with other distros as well.

### BEGIN INIT INFO
# Provides:          NRPE
# Required-Start:    $syslog $remote_fs
# Should-Start:      $time ypbind smtp
# Required-Stop:     $syslog $remote_fs
# Should-Stop:       ypbind smtp
# Default-Start:     3 5
# Default-Stop:      0 1 2 6
# Short-Description: NRPE XYZ daemon providing ZYX
# Description:       Start NRPE to allow XY and provide YZ
#    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!)
#    $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.

# Check for missing binaries (stale symlinks should not happen)
# Note: Special treatment of stop for LSB conformance

#      rc_status -u     display “unused” and exit with status 3
#      rc_failed        set local and overall rc status to failed
#      rc_failed <num>  set local and overall rc status to <num>

# with force-reload (in case signaling is not supported) are
