DH_INSTALLSYSTEMD(1)               Debhelper              DH_INSTALLSYSTEMD(1)

NAME
       dh_installsystemd - install systemd unit files

SYNOPSIS
       dh_installsystemd [debhelperoptions] [--restart-after-upgrade]
       [--no-stop-on-upgrade] [--no-enable] [--no-start] [--name=name]
       [unitfile...]

DESCRIPTION
       dh_installsystemd is a debhelper program that is responsible for
       installing package maintainer supplied systemd unit files.

       It also finds the service files installed by a package and generates
       preinst, postinst, and prerm code blocks for enabling, disabling,
       starting, stopping, and restarting the corresponding systemd services,
       when the package is installed, updated, or removed. These snippets are
       added to the maintainer scripts by dh_installdeb(1).

       deb-systemd-helper(1) is used to enable and disable systemd units, thus
       it is not necessary that the machine actually runs systemd during
       package installation time, enabling happens on all machines in order to
       be able to switch from sysvinit to systemd and back.

       dh_installsystemd operates on all unit files installed by a package.
       For only generating blocks for specific unit files, pass them as
       arguments, "dh_installsystemd quota.service". Specific unit files can
       be excluded from processing using the -X common debhelper(1) option.

FILES
       debian/package.mount, debian/package.path, debian/package@.path,
       debian/package.service, debian/package@.service, debian/package.socket,
       debian/package@.socket, debian/package.target, debian/package@.target,
       debian/package.timer, debian/package@.timer
           If any of those files exists, they are installed into
           lib/systemd/system/ in the package build directory.

       debian/package.tmpfile
           Only used in compat 12 or earlier.  In compat 13+, this file is
           handled by dh_installtmpfiles(1) instead.

           If this exists, it is installed into usr/lib/tmpfiles.d/ in the
           package build directory. Note that the "tmpfiles.d" mechanism is
           currently only used by systemd.

OPTIONS
       --no-enable
           Disable the service(s) on purge, but do not enable them on install.

           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.

       --name=name
           This option controls several things.

           It changes the name that dh_installsystemd uses when it looks for
           maintainer provided systemd unit files as listed in the "FILES"
           section.  As an example, dh_installsystemd --name foo will look for
           debian/package.foo.service instead of debian/package.service).
           These unit files are installed as name.unit-extension (in the
           example, it would be installed as foo.service).

           Furthermore, if no unit files are passed explicitly as command line
           arguments, dh_installsystemd will only act on unit files called
           name (rather than all unit files found in the package).

       --restart-after-upgrade
           Do not stop the unit file until after the package upgrade has been
           completed.  This is the default behaviour in compat 10.

           In earlier compat levels the default was to stop the unit file in
           the prerm, and start 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 service on upgrade.

       --no-start
           Do not start the unit file after upgrades and after initial
           installation (the latter is only relevant for services without a
           corresponding init script).

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

       unitfile...
           Only process and generate maintscripts for the installed unit files
           with the (base)name unit file.

           Note: dh_installsystemd will still install unit files from debian/
           but it will not generate any maintscripts for them unless they are
           explicitly listed in unitfile...

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