this has been discussed for a while, so I'd like to set automatic
restart for OpenStack services as a goal for Mitaka - milestone 1.
These are easy fixes, and by setting it to milestone 1, we'll have
more than enough time to test this and optimize.

I already created a trello card to track that effort, but I'd like to
get your feedback first.

can you describe what you mean here by automatic restart for services?

I'm worried what the implications would be for things that are running
under Pacemaker control in an HA environment, so I think we need more
details here

FWIW, this option is already enabled in some services, such as nova-api (https://github.com/openstack-packages/nova/blob/rpm-master/openstack-nova-api.service) where Restart=always. I've checked a Juno deployment, and that option was already set back then.

It shouldn´t affect pacemaker deployment, because we do override some of
those values via dbus config.

To clarify things, doesn’t it affect just nova-api because you have some special treatment for the service? or it would not affect you if applied to other units? [In that case we could go forward and set automatic restart policy there, while you could stick to your hooks to influence service restart behaviour.]
