Agreed with all the points here. We're adding bugs to the RC1 list for Nova faster than fixing them right now, so I don't think we can afford exceptions unless we really have to. I hate it though, because I definitely see how this could be very useful. It's just bad timing. -- Russell Bryant _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
