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]
