Comment 1 for bug 1394397

* This is internal glue, albeit configurable internal glue, but it doesn't really have an end-user impact. For that reason, it probably belongs in dev or API docs, more than openstack-manuals.
* As far as we can tell (and I understand this is a difficult thing to measure), this driver is only minimally in use, so the impact even to devs is pretty trivial

I have contacted the Nova PTL, Oslo PTL, and the Oslo docs liaison regarding this. Please feel free to raise an objection and reopen if you feel I've closed this in error.
