# UnitedLinux (UL) based Linux distributions. If you want to base your

# compliant Linux distributions, you either have to provide the rc.status

# functions from UL or change the script to work without them.

### BEGIN INIT INFO

# Provides:          clamd

# Required-Start:    $syslog $remote_fs

# X-UnitedLinux-Should-Start: $time ypbind sendmail

# Required-Stop:     $syslog $remote_fs

# X-UnitedLinux-Should-Stop: $time ypbind sendmail

# Default-Start:     3 5

# Default-Stop:      0 1 2 6

# Short-Description: virus scanner daemon

# Description:       Start the clamd virus scanner daemon

### END INIT INFO

# 

# Any extensions to the keywords given above should be preceeded by 

# X-VendorTag- (X-UnitedLinux- for us) according to LSB.

# 

# Notes on Required-Start/X-UnitedLinux-Should-Start:

# * There are two different issues that are solved by Required-Start

#    and X-UnitedLinux-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 X-UnitedLinux-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/X-UnitedLinux-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.

# * X-UnitedLinux-Should-Start/Stop are not part of LSB (as of 1.3)

#   but official Should-Start/Stop tags are in discussion (1.9).

#   insserv does support these as well.

# * 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.
