 # Common code for systemd based services.
 #
 # Prior to inheriting this class, recipes can define services like this:
 #
 # SYSTEMD_SERVICE:${PN} = "foo.service bar.socket baz@.service"
 #
 # and these files will be added to the main package if they exist.
 #
 # Alternatively this class can just be inherited and
 # ${PN}.service will be added to the main package.
 #
 # Other variables:
 # INHIBIT_SYSTEMD_RESTART_POLICY_${unit}
 #    Inhibit the warning that is displayed if a service unit without a
 #    restart policy is detected.
 #
 # SYSTEMD_SUBSTITUTIONS = "var:val:file"
 #    A specification for making python style {format} string
 #    substitutions where:
 #      var: the format string to search for
 #      val: the value to replace with

 #
 # SYSTEMD_USER_${PN}.service = "foo"
 # SYSTEMD_USER_${unit}.service = "foo"
 #    The user for the unit/package.
 #
 # SYSTEMD_ENVIRONMENT_FILE:${PN} = "foo"
 #    One or more environment files to be installed.
 #
 # SYSTEMD_LINK:${PN} = "tgt:name"
 #    A specification for installing arbitrary links in
 #    the ${systemd_system_unitdir} namespace, where:
 #      tgt: the link target
 #      name: the link name, relative to ${systemd_system_unitdir}

 #    A specification for installing unit overrides where:

 #
 #    Typically SYSTEMD_SUBSTITUTIONS is used to deploy a range
