I'm not so sure, you seem to have "overcloud" at the end of all three
controller entries?

Sure but you specifically acknowledge it is one of the things you have
changed so I would be inclined to revert that change and see if the
deploy works.

I like the jump release idea but I really would be inclined to run the
newer code as you can always put the upgrade testing into the Newton
release. In a few months Liberty will no longer be supported and I'd be
inclined not to carry the technical debt from an earlier release into a
production deployment, unless you are intending this for testing only?

We have more success with scheduler hints. So in our instackenv.json we
have:

            "capabilities": "node:controller-1,boot_option:local",

and then we have an environment file:

parameter_defaults:
    ControllerSchedulerHints:
        'capabilities:node': 'controller-%index%'
    NovaComputeSchedulerHints:
        'capabilities:node': 'compute-%index%'
    HostnameMap:
      overcloud-controller-0: overcloud-ctrl-customer-0
      overcloud-controller-1: overcloud-ctrl-customer-1
      overcloud-controller-2: overcloud-ctrl-customer-2
      overcloud-novacompute-0: overcloud-comp-customer-0
      overcloud-novacompute-1: overcloud-comp-customer-1

Not sure I understand this bit. Assuming an internal requirement rather
than a technical one?
