NAME

       dh_systemd_enable - enable/disable systemd unit files

SYNOPSIS

       dh_systemd_enable [debhelper options] [--no-enable] [--name=name] [unit file ...]

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   usr/lib/systemd/system/package.service   (or
           usr/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.

       debian/package.target, debian/package@.target
           If   this    exists,    it    is    installed    into    usr/lib/systemd/system/package.target    (or
           usr/lib/systemd/system/package@.target) in the package build directory.

       debian/package.socket, debian/package@.socket
           If    this    exists,    it    is    installed    into    usr/lib/systemd/system/package.socket   (or
           usr/lib/systemd/system/package@.socket) in the package build directory.

       debian/package.mount
           If this exists, it is  installed  into  usr/lib/systemd/system/package.mount  in  the  package  build
           directory.

       debian/package.path, debian/package@.path
           If     this    exists,    it    is    installed    into    usr/lib/systemd/system/package.path    (or
           usr/lib/systemd/system/package@.path) in the package build directory.

       debian/package.timer, debian/package@.timer
           If    this    exists,    it    is    installed    into    usr/lib/systemd/system/package.timer    (or
           usr/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.
