  _target_. _target_ takes the same format as the parameter to sys.powerctl. This is particularly

  intended to be used with the `exec_start` builtin for any must-have checks during boot.

  A service being stopped by init (e.g. using the `stop` or `class_reset` commands) is not

  considered a failure for the purpose of this setting.
