DESCRIPTION

14       dh_installsystemd is a debhelper program that is responsible for
15       installing package maintainer supplied systemd unit files.
16
17       It also finds the service files installed by a package and generates
18       preinst, postinst, and prerm code blocks for enabling, disabling,
19       starting, stopping, and restarting the corresponding systemd services,
20       when the package is installed, updated, or removed. These snippets are
21       added to the maintainer scripts by dh_installdeb(1).
22
23       deb-systemd-helper(1) is used to enable and disable systemd units, thus
24       it is not necessary that the machine actually runs systemd during
25       package installation time, enabling happens on all machines in order to
26       be able to switch from sysvinit to systemd and back.
27
28       dh_installsystemd operates on all unit files installed by a package.
29       For only generating blocks for specific unit files, pass them as
30       arguments, "dh_installsystemd quota.service". Specific unit files can
31       be excluded from processing using the -X common debhelper(1) option.

FILES

34       debian/package.mount, debian/package.path, debian/package@.path,
35       debian/package.service, debian/package@.service, debian/package.socket,
36       debian/package@.socket, debian/package.target, debian/package@.target,
37       debian/package.timer, debian/package@.timer
38           If any of those files exists, they are installed into
39           lib/systemd/system/ in the package build directory.
40
41       debian/package.tmpfile
42           Only used in compat 12 or earlier.  In compat 13+, this file is
43           handled by dh_installtmpfiles(1) instead.
44
45           If this exists, it is installed into usr/lib/tmpfiles.d/ in the
46           package build directory. Note that the "tmpfiles.d" mechanism is
47           currently only used by systemd.
48

OPTIONS

50       --no-enable
51           Disable the service(s) on purge, but do not enable them on install.
52
53           Note that this option does not affect whether the services are
54           started.  Please remember to also use --no-start if the service
55           should not be started.
56
57       --name=name
58           This option controls several things.
59
60           It changes the name that dh_installsystemd uses when it looks for
61           maintainer provided systemd unit files as listed in the "FILES"
62           section.  As an example, dh_installsystemd --name foo will look for
63           debian/package.foo.service instead of debian/package.service).
64           These unit files are installed as name.unit-extension (in the
65           example, it would be installed as foo.service).
66
67           Furthermore, if no unit files are passed explicitly as command line
68           arguments, dh_installsystemd will only act on unit files called
69           name (rather than all unit files found in the package).
70
71       --restart-after-upgrade
72           Do not stop the unit file until after the package upgrade has been
73           completed.  This is the default behaviour in compat 10.
74
75           In earlier compat levels the default was to stop the unit file in
76           the prerm, and start it again in the postinst.
77
78           This can be useful for daemons that should not have a possibly long
79           downtime during upgrade. But you should make sure that the daemon
80           will not get confused by the package being upgraded while it's
81           running before using this option.
82
83       --no-restart-after-upgrade
84           Undo a previous --restart-after-upgrade (or the default of compat
85           10).  If no other options are given, this will cause the service to
86           be stopped in the prerm script and started again in the postinst
87           script.
88
89       -r, --no-stop-on-upgrade, --no-restart-on-upgrade
90           Do not stop service on upgrade. This has the side-effect of not
91           restarting the service as a part of the upgrade.
92
93           If you want to restart the service with minimal downtime, please
94           use --restart-after-upgrade (default in compat 10 or later).  If
95           you want the service to be restarted but be stopped during the
96           upgrade, then please use --no-restart-after-upgrade (note the
97           "after-upgrade").
98
99           Note that the --no-restart-on-upgrade alias is deprecated and will
100           be removed in compat 14.  This is to avoid confusion with the
101           --no-restart-after-upgrade option.
102
103       --no-start
104           Do not start the unit file after upgrades and after initial
105           installation (the latter is only relevant for services without a
106           corresponding init script).
107
108           Note that this option does not affect whether the services are
109           enabled.  Please remember to also use --no-enable if the services
110           should not be enabled.
111
112       unit file ...
113           Only process and generate maintscripts for the installed unit files
114           with the (base)name unit file.
115
116           Note: dh_installsystemd will still install unit files from debian/
117           but it will not generate any maintscripts for them unless they are
118           explicitly listed in unit file ...

NOTES

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