As this part of the README indicates, the expectation was that this
part of the setup will be handled outside of the harness itself.

After all something also has to set up the keys to make sure that
the hosts can actually log into each other, right?

I'm a bit on the fence, some extra Review / support tags would be
useful, and it'd be useful to make the code in patch 3 less ugly.
Patches 1 and 2 make sense.
