In the future, you may want to start a new thread on
openstack-infra at lists.openstack.org for general Zuul questions.

I've changed the CC list and subject of this message to redirect the
conversation there.

We have not released Zuul v3 yet and we don't recommend that folks use
it yet unless they want to contribute to developing it.  Installation
and configuration is currently more difficult than we would like, and
the code base is still rapidly changing.  We will send out announcements
when it is ready for general use (including OpenStack third-party CI).
This may or may not apply to you, but I wanted to reiterate it for
anyone else reading.  Thanks for trying it out.  :)

You will need a newer version of bubblewrap.  Attempting to run with an
older one will cause Zuul not to behave as expected.  I believe
OpenStack-infra uses a PPA with a more recent version.

I believe that zuul_return is only expected to work on the executor, so
you may need to delegate this play to 'localhost' to ensure it does not
run on the remote node.

I'm not sure about this.  It might be related to the persistent SSH
connections which are constructed by the setup task and then used by
later playbook invocations.  I'd start by correcting the bubblewrap
issue and see if this changes.

Not yet, but we hope to have something like that before release.
