Ok, this is the easy part, and also what the vancouver-proposal included, the
difference comes in how the minority-arches are handled, and my proposal is a
'including' proposal, while the vancouver-proposal was 'excluding'.
4) each non-tier1 arches will have its own testing infrastructure, which
would take both unstable and testing in account.
5) packages are built out of unstable into an arch-specific unstable binary
repository on a separate machine (altough many minority arches may share this
infrastructure).
