Correct. As long as SCR is not running, components (and services implemented as components) are not active. BUT: Any service must be prepared to act upon the situation, that a service is missing. This is part of the OSGi service design AFAIUI. > As soon as SCR was up and running everything was fine. > > And I think there were similar issues with the configadmin service.

Similar case here: A service requiring configuraiton must be prepared to the situation, that the ConfigurationAdmin is not active and should act upon it as appropriate: Either use default settings or wait for real configuration to arrive.
