Note that #2 is a subset of #1. The only potential advantage of including #1 is efficiency: We can do #1 in one API call and bail early if it fails; but if it passes, we have to do #2 anyway, which is multiple steps. So would we rather save one step in the "good path" or potentially N-1 steps in the failure case? IMO the cost of the additional dev/test to implement #1 is higher than that of the potential extra API calls. (TL;DR: just implement #2.) -efried __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
