Comment 3 for bug 1604039

Actually, it's dlrn --local in https://github.com/openstack-infra/tripleo-ci/blob/master/scripts/tripleo.sh#L361

--local does NOT reset local branches to what is specified by distro and source
parameters in projects.ini, you need have rpm-mitaka in _distro checkout to match stable/mitaka source.
But this is all using internal implementation details of DLRN tool and RDO Trunk repositories, tripleo should request features in https://github.com/openstack-packages/dlrn/issues to have a stable interface e.g. DELOREAN_DEV=1 has no effect[1] and rpm-RELEASE are going away [2]
