Comment 11 for bug 1553617

It seems we're a little fragile about the rack controller registration process to the region controller. I would have thought it would be a simple two-phase process, starting on the region controller:

  $ maas-region add-rackd
  Now run "maas-rack register t0k1n-one-thyme http://192.168.3.34/" on the rack controller.

Then on the rack controller:

  $ maas-rack register t0k1n... http://192.../
  Rack controller registered to "garage" region.

At that stage, I would think the rack controller could update the region controller about its interfaces.
