I will push my changes as-is but they need revisiting/testing once the cloud-init bug has been fixed.

I haven't made any progress with this and am not currently working on it. Note: I believe this will also affect KVM containers/machines too.

This has been tested against LP #1603473. Will do some further testing tomorrow on the public clouds and raise a PR.
