Unfortunately, I was unable to reproduce this bug in MOS 7.0 deployment (Ubuntu). When applying the manifest which creates user 'nova' in debug mode we can see that it checks if user 'nova' already exists before creation. It means that this manifest is idempotent. For now this bug seems to me to be invalid, but maybe I'm wrong? Maybe someone was able to reproduce this bug?
