That was the benefit of my system over what you are talking about, there was no dependency on a global state or centralized control surface. Each worker was autonomous and self contained and had enough intelligence to bring itself to the desired state on its own. All you had to do was one line curl|bash install my service and it would take care of the rest without any other external dependencies. No worries about having to have ansible try to connect over and over again until things were working. It would just magically fix itself.

Again, many ways to skin the cat, but at the end of the day, this solution really worked extremely well. I would do it again in a heartbeat.
