After I bootstrap or upgrade my controller with --build-agent it changes the agent-version from 2.2.6 to 2.2.6.1 (I backported the patch), and I am able to add machines with the same architecture from my MaaS server, but when I attempt to add a machine with a different architecture wild things happen. Every machine matching the constraints is added and then almost immediately released once juju realizes that the architecture is different and it does not have an agent already built. Is there a way to hard code the build version such that when I bootstrap with build-agent it shows as 2.2.6? Regards, Matt Dirba 512-779-4696 On Mon, Dec 4, 2017 at 9:38 PM, John A Meinel
