It defaulted to mesh-host.service. What packaging/ ships is nox-mesh-host.service,
so on any machine with the packaged unit installed the installer looked for
something absent and told the operator a real machine needs it installed — when
it was installed, under the name the installer was not using.
Only the lab missed it, because the lab passes --host-in-background and never
names a unit at all.
