  52  * Rules regarding adding further high level targets like the above:
  53  *
  54  * - Be conservative, only add more of these when we really need
  55  *   them. We need strong usecases for further additions.
  56  *
  57  * - When there can be multiple implementations running side-by-side,
  58  *   it needs to be a .target unit which can pull in all
  59  *   implementations.
  60  *
  61  * - If something can be implemented with socket activation, and
  62  *   without, it needs to be a .target unit, so that it can pull in
  63  *   the appropriate unit.
  64  *
  65  * - Otherwise, it should be a .service unit.
  66  *
  67  * - In some cases it is OK to have both a .service and a .target
  68  *   unit, i.e. if there can be multiple parallel implementations, but
  69  *   only one is the "system" one. Example: syslog.
  70  *
  71  * Or to put this in other words: .service symlinks can be used to
  72  * arbitrate between multiple implementations if there can be only one
  73  * of a kind. .target units can be used to support multiple
  74  * implementations that can run side-by-side.
