That's fair I suppose. It just felt a bit like adding dependencies in
the wrong direction, and I would prefer to see the undercloud image
generated directly via tripleo-ci.
Isn't the plan to push more of the Delorean package git repo sources
under the OpenStack namespace in the future? If so, and things are
moving in that direction then I figured it would be better to have
less dependencies on the RDO side, and use as much of the existing
tripleo-ci as possible.
I was advocating for using tripleo-ci to build the undercloud image,
because we know it can and already does (we just doesn't save it), so
we should default to using tripleo-ci instead of RDO CI. tripleo-ci
doesn't build a whole delorean snapshot of master today (we only build
a small subset of the packages we're testing for that CI run), so in
that case, we use the RDO hosted one. I'm not saying tripleo-ci should
build a whole deloean repo by any means. Just that in the specific
case of the undercloud image, tripleo-ci is more or less already
building that, so we should save and reuse it.

I actually think that the trunk packaging shouldn't ever do that. It
should be 100% straight from trunk with no patches.
