Comment 15 for bug 2065700

Juju has space support on the manual provider, but it works in a slightly esoteric way due to the fact there is no real "provider" to detect the subnets from.

As machines are added, Juju will accumulate any subnets it sees and add them to its collection.

These can subsequently be carved into spaces.

Juju does have hierarchical rules for choosing a preferred address, but if 2 addresses have the same scope (local-cloud for example) there is a lexicographically sorted choice.

Feel free to get hold of me direct on Matrix/Mattermost if it would help to look at something in-situ.
