  70  * Rules regarding adding further high level targets like the above:
  71  *
  72  * - Be conservative, only add more of these when we really need
  73  *   them. We need strong usecases for further additions.
  74  *
  75  * - When there can be multiple implementations running side-by-side,
  76  *   it needs to be a .target unit which can pull in all
  77  *   implementations.
  78  *
  79  * - If something can be implemented with socket activation, and
  80  *   without, it needs to be a .target unit, so that it can pull in
  81  *   the appropriate unit.
  82  *
  83  * - Otherwise, it should be a .service unit.
  84  *
  85  * - In some cases it is OK to have both a .service and a .target
  86  *   unit, i.e. if there can be multiple parallel implementations, but
  87  *   only one is the "system" one. Example: syslog.
  88  *
  89  * Or to put this in other words: .service symlinks can be used to
  90  * arbitrate between multiple implementations if there can be only one
  91  * of a kind. .target units can be used to support multiple
  92  * implementations that can run side-by-side.
