I think that using a tested combination of client and agent is the most sensible default behaviour. We test that client 1.18.0 is compatible with agent 1.18.0. We don't test that client 1.18.0 is compatible with 1.18.1, 1.18.2, etc. I don't think that's worth the resources. (We do, however, test to ensure that upgrades work when the client is upgraded first.) >> If you're bootstrapping 1.18.0 and you don't want the machine >> agent to upgrade to the most recent patch level, you can override >> that behaviour by adding this to environments.yaml: > agent-version: 1.18.0 > >> Is that a reasonable solution? I don't think that is reasonable. It is the wrong default. Users should be able to expect that juju will always behave the same if they don't explicitly upgrade it. Installing a different agent runs the risk of incompatibility or changes in behaviour. The default should be a consistent experience. It is the wrong configuration method. bootstrap should support a - --version, like juju-upgrade. In order to specify agent-version, we would have to rewrite environments.yaml every time our desired version changed. Since we test both the stable and devel series our target version changes frequently. We could potentially rewrite it for every test run. We might lose the comments or formatting in the process of rewriting. Constantly rewriting environments.yaml is risky and gross.
