Hi, In devstack we have two more or less overlapping lib for deploying Neutron: lib/neutron and lib/neutron-legacy. lib/neutron-legacy was recently "undeprecated" (see [0]), and Openstack CI mostly (fully?) uses it. To avoid double maintenance, and confusion in settings we would like to deprecate lib/neutron, for recent discussions see [1] and [2]. The plan is to keep lib/neutron for 2 cycles (that will be AA or the release after Z) and delete lib/neutron then, and rename lib/neutron-legacy to lib/neutron. As You can see from the discussions below there are questions like how to name the processes, log-files etc..., as lib/neutron-legacy uses q-* and lib/neutron uses neutron-* names. The best would be to keep both in the long term (we love q-* as historical tradition, but neutron-* looks like so fresh and modern;)) If you have any thoughts suggestions or questions please answer to this mail or comment on the deprecation patch: [3] [0]: https://review.opendev.org/c/openstack/devstack/+/704829 [1]: https://meetings.opendev.org/meetings/networking/2022/networking.2022-01-04-...
