Comment 2 for bug 1696835

We need to update the help text, because I'm pretty sure it is "juju bootstrap --agent-version X" rather than "--config" at this point.

As for RC vs Stable, we still have the bug where if you're using a 'devel' version (anything with an 'rc/beta/etc' then it only sees beta agents as targets for deploy).

Also for *bootstrap* people have generally pushed pretty hard that we have to bootstrap the exact version as the client, and then possibly 'upgrade' to the requested version. And since you're using a newer client, we probably wouldn't let you downgrade the controller anyway.
(For example, 2.2 breaks bootstrap wrt 2.1 because it added a new mandatory field, so a 2.1 client couldn't bootstrap a 2.2 agent anyway, you have to go through the upgrade step.)

I think the docs we could fix, actually selecting the agent version is a bit trickier to support in all cases.

Generally within .patch versions, we could probably do it, but major.minor is probably not ever really supported.
