.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBdh_installinit\fR [\fIdebhelper options\fR] [\fB\-\-name=\fR\fIname\fR] [\fB\-n\fR] [\fB\-R\fR] [\fB\-r\fR] [\fB\-d\fR] [\fB\-\-\fR \fIparams\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBdh_installinit\fR is a debhelper program that is responsible for
installing init scripts with associated defaults files.  In
compatibility levels up to and including 10, \fBdh_installinit\fR will
also install some systemd related files provided by the debian
packaging (see the \*(L"\s-1FILES\*(R"\s0 section below).  In compatibility levels
up to and including 11, \fBdh_installinit\fR will also handle upstart
jobs provided in the debian packaging (see the \*(L"\s-1FILES\*(R"\s0 for more
information on this as well).
.PP
It also automatically generates the \fIpostinst\fR and \fIpostrm\fR and \fIprerm\fR
commands needed to set up the symlinks in \fI/etc/rc*.d/\fR to start and stop
the init scripts.
.PP
In compat 10 or earlier: If a package only ships a systemd service
file and no sysvinit script is provided, you may want to exclude the
call to dh_installinit for that package (e.g. via \fB\-N\fR).  Otherwise,
you may get warnings from lintian about init.d scripts not being
included in the package.
.SH "FILES"
.IX Header "FILES"
.IP "debian/\fIpackage\fR.init" 4
.IX Item "debian/package.init"
If this exists, it is installed into etc/init.d/\fIpackage\fR in the package
build directory.
.IP "debian/\fIpackage\fR.default" 4
.IX Item "debian/package.default"
If this exists, it is installed into etc/default/\fIpackage\fR in the package
build directory.
.IP "debian/\fIpackage\fR.upstart" 4
.IX Item "debian/package.upstart"
In compatibility level 11, this file will trigger an error with a reminder
about ensuring the proper removal of the upstart file in the previous package
version.  Please consider using the \*(L"rm_conffile\*(R" feature from
\&\fIdh_installdeb\fR\|(1) to ensure the proper removal of previous upstart files.
.Sp
In compatibility level 10, if this file exists, it is installed into
etc/init/\fIpackage\fR.conf in the package build directory.
.IP "debian/\fIpackage\fR.service" 4
.IX Item "debian/package.service"
If this exists, it is installed into lib/systemd/system/\fIpackage\fR.service in
the package build directory. Only used in compat levels 10 and below.
.IP "debian/\fIpackage\fR.tmpfile" 4
.IX Item "debian/package.tmpfile"
If this exists, it is installed into usr/lib/tmpfiles.d/\fIpackage\fR.conf in the
package build directory. (The tmpfiles.d mechanism is currently only used
by systemd.) Only used in compat levels 10 and below.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-n\fR, \fB\-\-no\-scripts\fR" 4
.IX Item "-n, --no-scripts"
Do not modify \fIpostinst\fR/\fIpostrm\fR/\fIprerm\fR scripts.
.IP "\fB\-o\fR, \fB\-\-only\-scripts\fR" 4
.IX Item "-o, --only-scripts"
Only modify \fIpostinst\fR/\fIpostrm\fR/\fIprerm\fR scripts, do not actually install
any init script, default files, upstart job or systemd service file. May be
useful if the file is shipped and/or installed by upstream in a way that
doesn't make it easy to let \fBdh_installinit\fR find it.
.Sp
\&\fBCaveat\fR: This will bypass all the regular checks and
\&\fIunconditionally\fR modify the scripts.  You will almost certainly want
to use this with \fB\-p\fR to limit, which packages are affected by the
call.  Example:
.Sp
.Vb 3
\& override_dh_installinit:
\&        dh_installinit \-pfoo \-\-only\-scripts
\&        dh_installinit \-\-remaining
.Ve
.IP "\fB\-R\fR, \fB\-\-restart\-after\-upgrade\fR" 4
.IX Item "-R, --restart-after-upgrade"
Do not stop the init script until after the package upgrade has been
completed.  This is the default behaviour in compat 10.
.Sp
In early compat levels, the default was to stop the script in the
\&\fIprerm\fR, and starts it again in the \fIpostinst\fR.
.Sp
This can be useful for daemons that should not have a possibly long
downtime during upgrade. But you should make sure that the daemon will not
get confused by the package being upgraded while it's running before using
this option.
.IP "\fB\-\-no\-restart\-after\-upgrade\fR" 4
.IX Item "--no-restart-after-upgrade"
Undo a previous \fB\-\-restart\-after\-upgrade\fR (or the default of compat
10).  If no other options are given, this will cause the service to be
stopped in the \fIprerm\fR script and started again in the \fIpostinst\fR
script.
.IP "\fB\-r\fR, \fB\-\-no\-stop\-on\-upgrade\fR, \fB\-\-no\-restart\-on\-upgrade\fR" 4
.IX Item "-r, --no-stop-on-upgrade, --no-restart-on-upgrade"
Do not stop init script on upgrade.  This has the side-effect of not
restarting the service as a part of the upgrade.
.Sp
If you want to restart the service with minimal downtime, please use
\&\fB\-\-restart\-after\-upgrade\fR (default in compat 10 or later).  If you want
the service to be restarted but be stopped during the upgrade, then please
use \fB\-\-no\-restart\-after\-upgrade\fR (note the \*(L"after-upgrade\*(R").
.Sp
Note that the \fB\-\-no\-restart\-on\-upgrade\fR alias is deprecated and will
be removed in compat 12.  This is to avoid confusion with the
\&\fB\-\-no\-restart\-after\-upgrade\fR option.  The \fB\-\-no\-stop\-on\-upgrade\fR
variant was introduced in debhelper 10.2 (included in Debian stretch).
.IP "\fB\-\-no\-start\fR" 4
.IX Item "--no-start"
Do not start the init script on install or upgrade, or stop it on removal.
Only call \fBupdate\-rc.d\fR. Useful for rcS scripts.
.IP "\fB\-\-no\-enable\fR" 4
.IX Item "--no-enable"
Disable the init script on purge, but do not enable them on install.
This implies a versioned dependency on \fBinit-system-helpers (>=
1.51)\fR as it is the first (functional) version that supports
\&\fBupdate\-rc.d <script> defaults-disabled\fR.
.Sp
\&\fBNote\fR that this option does not affect whether the services are
started.  Please remember to also use \fB\-\-no\-start\fR if the service
should not be started.
.Sp
Cannot be combined with \fB\-u\fR\fIparams\fR,
\&\fB\-\-update\-rcd\-params=\fR\fIparams\fR, or \fB\-\-\fR \fIparams\fR.
.IP "\fB\-d\fR, \fB\-\-remove\-d\fR" 4
.IX Item "-d, --remove-d"
Remove trailing \fBd\fR from the name of the package, and use the result for the
filename the upstart job file is installed as in \fIetc/init/\fR , and for the
filename the init script is installed as in etc/init.d and the default file
is installed as in \fIetc/default/\fR. This may be useful for daemons with names
ending in \fBd\fR. (Note: this takes precedence over the \fB\-\-init\-script\fR parameter
described below.)
.IP "\fB\-u\fR\fIparams\fR \fB\-\-update\-rcd\-params=\fR\fIparams\fR" 4
.IX Item "-uparams --update-rcd-params=params"
.PD 0
.IP "\fB\-\-\fR \fIparams\fR" 4
.IX Item "-- params"
.PD
Pass \fIparams\fR to \fIupdate\-rc.d\fR\|(8). If not specified, \fBdefaults\fR (or
\&\fBdefaults-disabled\fR with \fB\-\-no\-enable\fR) will be passed to
\&\fIupdate\-rc.d\fR\|(8).
.Sp
Cannot be combined with \fB\-\-no\-enable\fR.
.IP "\fB\-\-name=\fR\fIname\fR" 4
.IX Item "--name=name"
Install the init script (and default file) as well as upstart job file
using the filename \fIname\fR instead of the default filename, which is
the package name. When this parameter is used, \fBdh_installinit\fR looks
for and installs files named \fIdebian/package.name.init\fR,
\&\fIdebian/package.name.default\fR and \fIdebian/package.name.upstart\fR
instead of the usual \fIdebian/package.init\fR, \fIdebian/package.default\fR and
\&\fIdebian/package.upstart\fR.
.IP "\fB\-\-init\-script=\fR\fIscriptname\fR" 4
.IX Item "--init-script=scriptname"
Use \fIscriptname\fR as the filename the init script is installed as in
\&\fIetc/init.d/\fR (and also use it as the filename for the defaults file, if it
is installed). If you use this parameter, \fBdh_installinit\fR will look to see
if a file in the \fIdebian/\fR directory exists that looks like
\&\fIpackage.scriptname\fR and if so will install it as the init script in
preference to the files it normally installs.
.Sp
This parameter is deprecated, use the \fB\-\-name\fR parameter instead. This
parameter is incompatible with the use of upstart jobs.
.IP "\fB\-\-error\-handler=\fR\fIfunction\fR" 4
.IX Item "--error-handler=function"
Call the named shell \fIfunction\fR if running the init script fails. The
function should be provided in the \fIprerm\fR and \fIpostinst\fR scripts, before the
\&\fB#DEBHELPER#\fR token.
