FWIW, I think the byArch did a plain sort.Strings() which happens to pick amd64 because it is before all other in a typographical fashion. IIRC, it may have mutated a lot over time because the sorting was blocking bootstrap from working on ppc64 which was why it was removed. Also, on MaaS, MaaS doesn't seem to actually be giving us what arches are available, which is why every bootstrap gives a warning about "picking arbitrary tools", and we have an open bug that just "juju bootstrap" on an all-ppc64 MaaS doesn't work, you are required to specify the arch=ppc64 for it to work there.
