We should revisit the general design where to put it and how to use it. Most likely I can see the use case of moving augeasprivate to common/libraries as a public augeas library for all actors, and have a dedicated actor for the upgrade to produce configuration

If we want some additional things we would modify that actor and patches can be sent to that one.

This implies also the spec file needs to be updated to depend on those things

# self.log.info("Starting to process...")

self.consumed_msg = self.consume(AugeasInput).next()

  1. No sense to use member variables for this on self, there's no use for these
  2. Use next(self.consume(AugeasInput), None) which will give you None as a result if there's no message, that will help you to avoid having to process the input.
consumed_msg = next(self.consume(AugeasInput), None)
if consumed_msg:
    ...

self.consumed_msg = self.consume(AugeasInput).next()

metadata = augeasprivate.process_augeas_data(
self.consumed_msg, self.lenses_folder, self.augeas_tree

since, I already said that the constructor usage doesn't make sense, you can use the lenses_folder, and augeas_tree parts directly here.
