Comment 6 for bug 1512875

Sorry about the delay in response. We won't be addressing this specifically for 2.2. We're still trying to figure out how to concretely model things like Controller endpoints and 'ssh' access for machines and how it overlaps with spaces.

We have had both cases where people have asked specifically *for* the PXE network to be the one that gets used, and where people have aske for it *not* to be the one that it used. What we really need is a way for users to declare a space for us to use for things like access to machines.

It may be that we model this as a generic endpoint on all charms (like we currently have 'juju-info), but that doesn't really handle things like "juju add-machine" where you'd still like to declare the information about where 'ssh' should be accessed, but you don't have any applications running on that machine.
