Devstack has some half baked support for keystone templated service catalog. In an effort to clean up parts of devstack, we're dropping that - https://review.openstack.org/#/c/278333 However... this unfortunately led to some cargo culting, and everyone's devstack plugin is going to fail if we remove the KEYSTONE_CATALOG_BACKEND variable - http://codesearch.openstack.org/?q=KEYSTONE_CATALOG_BACKEND&i=nope&files=&repos= We'll keep the variable around until Newton opens up. In Newton, we will drop it. This is your warning to remove that if block and create your service entries unconditionally. -Sean -- Sean Dague http://dague.net
