It's just a set of (very large) JSON files in a well defined location. Very large, as in 48M for the one file that we need. Because it's so big, pulling that down each time you go to bootstrap isn't really reasonable. So for now, we're doing that at build time, and the information is still hard coded into the client. The process can be automated, so there shouldn't be a great lag time between updates and bringing them into a Juju release. We intend to update Juju later to periodically pull down the JSON file server-side, asynchronously, so a running controller will get the updates without us having to release a new Juju or you having to upgrade. Hope that clarifies things.
