14 dh_installsystemd is a debhelper program that is responsible for
15 installing package maintainer supplied systemd unit files.
16 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 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 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.
32
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 debian/package.tmpfile
42 If this exists, it is installed into usr/lib/tmpfiles.d/ in the
43 package build directory. Note that the "tmpfiles.d" mechanism is
44 currently only used by systemd.
45
47 --no-enable
48 Disable the service(s) on purge, but do not enable them on install.
49 Note that this option does not affect whether the services are
51 started. Please remember to also use --no-start if the service
52 should not be started.
53 --name=name
55 This option controls several things.
56 It changes the name that dh_installsystemd uses when it looks for
58 maintainer provided systemd unit files as listed in the "FILES"
59 section. As an example, dh_installsystemd --name foo will look for
60 debian/package.foo.service instead of debian/package.service).
61 These unit files are installed as name.unit-extension (in the
62 example, it would be installed as foo.service).
63 Furthermore, if no unit files are passed explicitly as command line
65 arguments, dh_installsystemd will only act on unit files called
66 name (rather than all unit files found in the package).
67 --restart-after-upgrade
69 Do not stop the unit file until after the package upgrade has been
70 completed. This is the default behaviour in compat 10.
71 In earlier compat levels the default was to stop the unit file in
73 the prerm, and start it again in the postinst.
74 This can be useful for daemons that should not have a possibly long
76 downtime during upgrade. But you should make sure that the daemon
77 will not get confused by the package being upgraded while it's
78 running before using this option.
79 --no-restart-after-upgrade
81 Undo a previous --restart-after-upgrade (or the default of compat
82 10). If no other options are given, this will cause the service to
83 be stopped in the prerm script and started again in the postinst
84 script.
85 -r, --no-stop-on-upgrade, --no-restart-on-upgrade
87 Do not stop service on upgrade.
88 --no-start
90 Do not start the unit file after upgrades and after initial
91 installation (the latter is only relevant for services without a
92 corresponding init script).
93 Note that this option does not affect whether the services are
95 enabled. Please remember to also use --no-enable if the services
96 should not be enabled.
97 unit file ...
99 Only process and generate maintscripts for the installed unit files
100 with the (base)name unit file.
101 Note: dh_installsystemd will still install unit files from debian/
103 but it will not generate any maintscripts for them unless they are
104 explicitly listed in unit file ...
105
107 This command is not idempotent. dh_prep(1) should be called between
108 invocations of this command (with the same arguments). Otherwise, it
109 may cause multiple instances of the same text to be added to maintainer
110 scripts.
