DH_SYSTEMD_ENABLE(1) Debhelper DH_SYSTEMD_ENABLE(1)
NAME
dh_systemd_enable - enable/disable systemd unit files
SYNOPSIS
dh_systemd_enable [debhelperoptions] [--no-enable] [--name=name] [unitfile...]
DESCRIPTION
dh_systemd_enable is a debhelper program that is responsible for enabling and disabling systemd unit files.
In the simple case, it finds all unit files installed by a package (e.g. bacula-fd.service) and enables them. 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.
In the complex case, you can call dh_systemd_enable and dh_systemd_start manually (by overwriting the debian/rules targets) and specify
flags per unit file. An example is colord, which ships colord.service, a dbus-activated service without an [Install] section. This service
file cannot be enabled or disabled (a state called "static" by systemd) because it has no [Install] section. Therefore, running
dh_systemd_enable does not make sense.
For only generating blocks for specific service files, you need to pass them as arguments, e.g. dh_systemd_enable quota.service and
dh_systemd_enable --name=quotarpc quotarpc.service.
FILES
debian/package.service, debian/package@.service
If this exists, it is installed into lib/systemd/system/package.service (or lib/systemd/system/package@.service) in the package build
directory.
debian/package.tmpfile
If this exists, it is installed into usr/lib/tmpfiles.d/package.conf in the package build directory. (The tmpfiles.d mechanism is
currently only used by systemd.)
debian/package.target, debian/package@.target
If this exists, it is installed into lib/systemd/system/package.target (or lib/systemd/system/package@.target) in the package build
directory.
debian/package.socket, debian/package@.socket
If this exists, it is installed into lib/systemd/system/package.socket (or lib/systemd/system/package@.socket) in the package build
directory.
debian/package.mount
If this exists, it is installed into lib/systemd/system/package.mount in the package build directory.
debian/package.path, debian/package@.path
If this exists, it is installed into lib/systemd/system/package.path (or lib/systemd/system/package@.path) in the package build
directory.
debian/package.timer, debian/package@.timer
If this exists, it is installed into lib/systemd/system/package.timer (or lib/systemd/system/package@.timer) in the package build
directory.
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. That is controlled by dh_systemd_start(1) (using e.g. its
--no-start option).
--name=name
Install the service file as name.service instead of the default filename, which is the package.service. When this parameter is used,
dh_systemd_enable looks for and installs files named debian/package.name.service instead of the usual debian/package.service.
NOTES
Note that 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.
Note that dh_systemd_enable should be run before dh_installinit. The default sequence in dh does the right thing, this note is only
relevant when you are calling dh_systemd_enable manually.
