Comment 2 for bug 1900439

I find the behavior confusing, if I do, others surely will!

Let's put it another way if you pass in both an agent-metadata-url and an agent-version I'm pretty sure you shouldn't be looking elsewhere! You're telling Juju to look here for the agent-version and it's not there and you go look somewhere else, then we bootstrap, but we do it with something they don't want.

We didn't find the agent in the metadata, we should error out fast rather than bootstrap with something they didn't want.
