- # 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: FOO
- # Required-Start: $syslog $remote_fs
- # Should-Start: $time ypbind sendmail
- # Required-Stop: $syslog $remote_fs
- # Should-Stop: $time ypbind sendmail
- # Default-Start: 3 5
- # Default-Stop: 0 1 2 6
- # Short-Description: FOO XYZ daemon providing ZYX
- # Description: Start FOO 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.
