Operator: "You are not following naming conventions." Renamed the two
random-named vr1-dc0-region machines to convention (hostname == libvirt
domain == power_id, lib-hosts:26): known-marten->vr1-dc0-tailscale-01,
subtle-grouse->vr1-dc0-juju-01. All 11 dc0-region machines now vr1-dc0-*.
Cosmetic to tooling (carve/power resolve by boot MAC); load-bearing for
operability. changelog Item 6 + CURRENT-STATE note.
