NAME

       dh_installinit - install service init files into package build directories

SYNOPSIS

       dh_installinit [debhelper options] [--name=name] [-n] [-R] [-r] [-d] [-- params]

DESCRIPTION

       dh_installinit is a debhelper program that is responsible for installing init scripts with
       associated defaults files.  In compatibility levels up to and including 10, dh_installinit
       will also install some systemd related files provided by the debian packaging (see the
       "FILES" section below).  In compatibility levels up to and including 11, dh_installinit
       will also handle upstart jobs provided in the debian packaging (see the "FILES" for more
       information on this as well).

       It also automatically generates the postinst and postrm and prerm commands needed to set
       up the symlinks in /etc/rc*.d/ to start and stop the init scripts.

       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 -N).  Otherwise, you may get warnings from lintian about init.d scripts not
       being included in the package.

FILES

       debian/package.init
           If this exists, it is installed into etc/init.d/package in the package build
           directory.

       debian/package.default
           If this exists, it is installed into etc/default/package in the package build
           directory.

       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 "rm_conffile" feature from dh_installdeb(1) to ensure the
           proper removal of previous upstart files.

           In compatibility level 10, if this file exists, it is installed into
           etc/init/package.conf in the package build directory.

       debian/package.service
           If this exists, it is installed into usr/lib/systemd/system/package.service in the
           package build directory. Only used in compat levels 10 and below.

       debian/package.tmpfile
           If this exists, it is installed into usr/lib/tmpfiles.d/package.conf in the package
           build directory. Only used in compat levels 10 and below.

OPTIONS

       -n, --no-scripts
           Do not modify postinst/postrm/prerm scripts.

       -o, --only-scripts
           Only modify postinst/postrm/prerm 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
           dh_installinit find it.

           Caveat: This will bypass all the regular checks and unconditionally modify the
           scripts.  You will almost certainly want to use this with -p to limit, which packages
           are affected by the call.  Example:

            override_dh_installinit:
                   dh_installinit -pfoo --only-scripts
                   dh_installinit --remaining

       -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.

           In early compat levels, the default was to stop the script in the prerm, and starts it
           again in the postinst.

           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.

       --no-restart-after-upgrade
           Undo a previous --restart-after-upgrade (or the default of compat 10).  If no other
           options are given, this will cause the service to be stopped in the prerm script and
           started again in the postinst script.

       -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.

           If you want to restart the service with minimal downtime, please use
           --restart-after-upgrade (default in compat 10 or later).  If you want the service to
           be restarted but be stopped during the upgrade, then please use
           --no-restart-after-upgrade (note the "after-upgrade").

           Note that the --no-restart-on-upgrade alias is deprecated and will be removed in
           compat 12.  This is to avoid confusion with the --no-restart-after-upgrade option.
           The --no-stop-on-upgrade variant was introduced in debhelper 10.2 (included in Debian
           stretch).

       --no-start
           Do not start the init script on install or upgrade, or stop it on removal.  Only call
           update-rc.d. Useful for rcS scripts.

       --no-enable
           Disable the init script on purge, but do not enable them on install.  This implies a
           versioned dependency on init-system-helpers (>= 1.51) as it is the first (functional)
           version that supports update-rc.d <script> defaults-disabled.

           Note that this option does not affect whether the services are started.  Please
           remember to also use --no-start if the service should not be started.

           Cannot be combined with -uparams, --update-rcd-params=params, or -- params.

       -d, --remove-d
           Remove trailing d from the name of the package, and use the result for the filename
           the upstart job file is installed as in etc/init/ , and for the filename the init
           script is installed as in etc/init.d and the default file is installed as in
           etc/default/. This may be useful for daemons with names ending in d. (Note: this takes
           precedence over the --init-script parameter described below.)

       -uparams --update-rcd-params=params
       -- params
           Pass params to update-rc.d(8). If not specified, defaults (or defaults-disabled with
           --no-enable) will be passed to update-rc.d(8).

           Cannot be combined with --no-enable.

       --name=name
           Install the init script (and default file) as well as upstart job file using the
           filename name instead of the default filename, which is the package name. When this
           parameter is used, dh_installinit looks for and installs files named
           debian/package.name.init, debian/package.name.default and debian/package.name.upstart
           instead of the usual debian/package.init, debian/package.default and
           debian/package.upstart.

       --init-script=scriptname
           Use scriptname as the filename the init script is installed as in etc/init.d/ (and
           also use it as the filename for the defaults file, if it is installed). If you use
           this parameter, dh_installinit will look to see if a file in the debian/ directory
           exists that looks like package.scriptname and if so will install it as the init script
           in preference to the files it normally installs.

           This parameter is deprecated, use the --name parameter instead. This parameter is
           incompatible with the use of upstart jobs.

       --error-handler=function
           Call the named shell function if running the init script fails. The function should be
           provided in the prerm and postinst scripts, before the #DEBHELPER# token.

NOTES

       Note that this command is not idempotent. dh_prep(1) should be called between invocations
       of this command. Otherwise, it may cause multiple instances of the same text to be added
       to maintainer scripts.
