I have no objection if you want to give it a try. However it is basically a
separate problem, and I don't think this series would depend on that. The reason
is that setting up guest ssh is not part of the "build env setup" task, but is
the trickiest part here.  As you can see in the ubuntu image, "cloud-init" is
used just for that, and the build env is simply doing a "apt-get build-dep"; if
it were for Fedora the command is a dnf counterpart.  (I probably could have
removed the dev packages in BSD templates and add code to the *bsd scripts to
locally install packages after downloading.)

Ansible is probably an overkill anyway because what we'd have in the playbooks
are command lists to install package sets. Shell scripts can do that just fine,
this is not what ansible is great for, IMO (of course I'd be wrong if there is
an ansible module called 'build-dep' that supports many OSes, I'm not an ansible
expert either).
