Subject: core: always coldplug units that are triggered by other units before
|
||||
those
|
||||
|
||||
Let's make sure that we don't enqueue triggering jobs for units before
|
||||
those units are actually fully loaded.

Subject: core: coldplug all units which participate in jobs during
|
||||
coldplugging
|
||||
|
||||
This is yet another attempt to fix coldplugging order (more especially,
|
||||
the problem which happens when one creates a job during coldplugging and
|
||||
it references a not-yet-coldplugged unit).
|
||||
|
||||
Now we forcibly coldplug all units which participate in jobs. This
|
||||
is a superset of previously implemented handling of the UNIT_TRIGGERS
|
||||
dependencies, so that handling is removed.
