Is this true: there two pieces of information that are important which networks to tell the API to bind to the instance, and what network's IP address to use to connect to the instance after it is created?

If so, are we presuming that the first network listed is the one we want to boot from?

And further, if so, do we need to be more explicit about this in some way, e.g. "The first network listed will be used to connect to the instance to bootstrap it."
