Seems fine to me. This is exactly what i intended.

I'll try. Seems a good solution, but can't understand why this will
impact if hosts file is correct and hosts can talk each other using
the assigned name.

I already tried this. I had a strange issue while deploying computing
nodes (puppet errors, don't remember exactly what). That's why i
returned to my previous mirror since i had successfully deployed a 1+3
setup without issues.

I'd like to complete the setup with Liberty. We are playing also with
other distributions (mainly commercial) that are proposing Liberty and
we'd like to have everything aligned. Additionally we'd try a forward
jump in place, to make a funny release-upgrade test and see what
happens.

I agree, i'll try.

That file has simply this inside:

parameter_defaults:
        ControllerHostnameFormat: 'opsctrl%index%'
        ComputeHostnameFormat: 'opskvmsvil%index%'


That is simply because overcloud-novacompute-0 was too long name
