Comment 1 for bug 1543150

Thanks Chris. I have seen this same behavior many times and reporting this as confirmed. It has been reported in the past as well. I'm not sure it can be fixed in an automated way for Liberty because it may require significant changes to the playbooks. After discussion with inc0, we think it will be solvable in Mitaka via a "kolla-ansible reconfigure" feature which could docker exec rm the config once lock file and restart containers that have configuration changes associated with them.

I think a backport may be difficult given the rate of change in Mitaka playbooks, but anything is possible :)
