>         Fail: Configuration parameter 'falcon-env' was not found in configurations dictionary!",
> The Blueprint configuration processor is not correctly handling the case of a component, such as Falcon, that includes "excluded" config references in its stack definition.  This appears to be a regression.  
> I'm working on a patch to resolve this, and will be submitting it shortly.
