 * Rules regarding adding further high level targets like the above:
 *
 * - Be conservative, only add more of these when we really need
 *   them. We need strong use cases for further additions.
 *
 * - When there can be multiple implementations running side-by-side,
 *   it needs to be a .target unit which can pull in all
 *   implementations.
 *
 * - If something can be implemented with socket activation, and
 *   without, it needs to be a .target unit, so that it can pull in
 *   the appropriate unit.
 *
 * - Otherwise, it should be a .service unit.
 *
 * - In some cases it is OK to have both a .service and a .target
 *   unit, i.e. if there can be multiple parallel implementations, but
 *   only one is the "system" one. Example: syslog.
 *
 * Or to put this in other words: .service symlinks can be used to
 * arbitrate between multiple implementations if there can be only one
 * of a kind. .target units can be used to support multiple
 * implementations that can run side-by-side.
