Comment 7 for bug 1697095

So you need to use the manual provider explicitly, you can't mix in any architecture that maas doesn't support with a maas provided environment? That seems...kind of not great actually. I've got this working but it's reliant on a relatively fragile set of circumstances for a correct deployment, i.e. the s390x node has to be the last thing to deploy and there must be no more deployable machines in maas, I was hoping to use architecture constraints to shore that piece of the deployment up. Are there any other constraints I can apply in this situation? I.e. is it possible to tag a machine added via add-machine perhaps?
