/*
* 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 usecases 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.
