      public void init(org.osgi.framework.BundleContext context, org.apache.felix.dm.DependencyManager dm) throws Exception
      Initialize our DependencyManager Runtime service. We depend on the OSGi LogService, and we track all started bundles which do have a "DependencyManager-Component" Manifest header. If the "dm.runtime.log=true" or "dm.runtime.packageAdmin=true" parameter is configured in the Felix config.properties then we'll use a required/temporal service dependency over the respective service. These temporal dependencies avoid us to be restarted if the respective service is temporarily unavailable (that is: when the service is updating). if the "dm.runtime.log" or "dm.runtime.packageAdmin" is not configured or it it is set to false, then we'll use an optional dependency over the respective service, in order to use a NullObject in case the service is not available.
