Add a synchronization point so that custom initramfs units can run after the root device becomes available, before it is fsck'd and mounted. This is useful for custom initramfs units that may modify the root disk partition table, where the root device is not known in advance (it's dynamically selected by the generators).

* 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.
