INSSERV(8) The SuSE boot concept INSSERV(8)
NAME
Insserv - Enable an installed system init script
SYNOPSIS
insserv [-v] [-d] [-f] [[/]path/to/init.d/]script ...
insserv [-v] [[/]path/to/init.d/]script[,start=<lvl1>[,<lvl2>]] ...
insserv [-v] -r [-d] [-f] [[/]path/to/init.d/]script ...
insserv -h
/usr/lib/lsb/install_initd [[/]path/to/init.d/script]
/usr/lib/lsb/remove_initd [[/]path/to/init.d/script]
DESCRIPTION
insserv enables an installed system init script (`boot script') by
reading the comment header of the script, e.g.:
### BEGIN INIT INFO
# Provides: boot_facility_1 [ boot_facility_2 ...]
# Required-Start: boot_facility_1 [ boot_facility_2 ...]
# Required-Stop: boot_facility_1 [ boot_facility_2 ...]
# Should-Start: boot_facility_1 [ boot_facility_2 ...]
# Should-Stop: boot_facility_1 [ boot_facility_2 ...]
# Default-Start: run_level_1 [ run_level_2 ...]
# Default-Stop: run_level_1 [ run_level_2 ...]
# Description: multiline_description
### END INIT INFO
and calculating the dependencies between all scripts. Please note,
that the Required-Stop, Should-Stop, and Default-Stop are ignored in
SuSE Linux, because the SuSE boot script concept uses a differential
link scheme (see init.d(7)). With known dependencies and runlevel(s)
insserv sets and reorders the corresponding symbolic links of the con-
cerned runlevels directories (see init.d(7)). Known runlevels are:
0 used for System halt
1 used for single user mode
2 used for local multiuser without remote network
3 used for full multiuser with network
4 reserved for local use
5 used for full multiuser with network and xdm
6 used for System reboot
S used during boot into single user mode
B used during boot before any other runlevel
insserv scans for System Facilities in the configuration file
/etc/insserv.conf and each file in the directory /etc/insserv.conf.d/.
Each line which begins with $ and a following name defines a system
facility accordingly to the Linux Standard Base Specification (LSB),
All names followed by such a system facility will declare the required
dependencies of the facility. Here is an example for
/etc/insserv.conf:
# All local filesystems are mounted
# (done during boot phase)
$local_fs boot
# Low level networking
$network network route
# Named is operational
$named named
# All remote filesystems are mounted
# (in some cases /usr may be remote).
$remote_fs $local_fs nfs
# System logger is operational
$syslog syslog
# All network daemons are running
$netdaemons portmap inetd
# Services which need to be interactive
<interactive> boot.crypto
Names starting with a `+' sign are marked as optional. If the service
with the name after the plus sign is available it will be used, if not
available it is ignored silently. Words beginning with < and ending
with > are keywords. Currently <interactive> is the only know keyword
for marking a service as an interactive one, e.g. a service which
requires a passphrase or password input during boot or runlevel change.
Beside the defined System Facilities in the configuration file
/etc/insserv.conf, insserv also knows the special facility $all. This
facility indicates that a service should be inserted at the end of all
services. Clearly all services using this facility will be grouped
into one starting order.
OPTIONS
Currently there are only four options for insserv.
-v, --verbose
Write out what is currently going on.
-n, --dryrun
Do not update symlinks.
-r, --remove
Remove the listed scripts from all runlevels.
-d, --default
Use default runlevels a defined in the scripts. This may
restore an edited runlevel link scheme.
-f, --force
Ignore if a required service is missed.
-h, --help
Print out short usage message.
But you may use the argument syntax described in the following section.
ARGUMENTS
[[/]path/to/init.d/]
Relative or absolute path to the init scripts base directory.
For the SuSE Linux boot concept, this defaults to /etc/init.d/
in compliance with the LSB specification. In this case insserv
does not add or remove a script to the runlevels declared in the
script headers, but may re-order the runlevels if the order of
the currently enabled scripts has changed (see option -d). Note
that if a relative path is used insserv has to be called from
the root directory.
[[/]path/to/init.d/]script ...
List of scripts which have to be added to the runlevels. If a
path is used it should point to the absolute or relative loca-
tion of the boot scripts. insserv checks for the existence of
these scripts. For the runlevels the information found in the
script is used.
[[/]path/to/init.d/]script[,start=<lvl1>[,<lvl2>]] ...
List of scripts which have to be added to the specified run-
levels to be started with. You may use this extension to over-
write the default values for start and stop runlevels of the
script. Note that <lvl1>, <lvl2>, ... are the known runlevels
explained above. The extension ,stop=<lvl1>[,<lvl2>]] is possi-
ble but ignored on SuSE Linux.
-r [[/]path/to/init.d/]script ...
List of scripts which should be removed from the runlevels. If a
path is used it should point to the absolute or relative loca-
tion of the boot scripts. insserv checks for the existence of
these scripts.
EXIT CODES
The exit codes have the following conditions:
0 Service was successfully installed or removed
1 Service was not installed or removed
NOTE
Please be aware that the following patterns of boot script file names
will be not accepted by insserv:
*.local
*.rpm*
*.ba*
*.old
*.new
*.org
*.orig
*.save
*.swp
*.core
*~
with the wildcard character *. Beside this all boot script file names
beginning with one of the following characters
$.#%_+-\*[]^:()~
will be ignored.
BUGS
Boot script sometimes misses comments.
FILES
/etc/insserv.conf
configuration file for insserv which defines the LSB System
Facilities.
/etc/insserv.conf.d/
directory for further configuration files for declaring LSB Sys-
tem Facilities.
/etc/init.d/
path to the SuSE boot script base directory as required by the
Linux Standard Base Specification (LSB).
/etc/init.d/.depend.boot,
/etc/init.d/.depend.start,
/etc/init.d/.depend.stop
The make(1) like dependency files produced by insserv for boot
ing, starting, and stopping with the help of startpar(8).
