There are a couple of cases [1][2] I'm seeing where new Cinder volume drivers for Liberty are rebranding other volume drivers. This involves inheriting off another volume driver's class(es) and providing some config options to set the backend name, etc. Two problems: 1) There is a thought of no CI [3] is needed, since you're using another vendor's driver code which does have a CI. 2) IMO another way of satisfying a check mark of being OpenStack supported and disappearing from the community. What gain does OpenStack get from these kind of drivers? Discuss.
