test deployments using data obtained through the data model in VMs. caveats: - SSH currently has a `run` abstraction that the nixops4 model still lacks - the deployed (trivial) configuration on activation has not facilitated new ssh connections (for subsequent) updates, i.e. a more sophisticated configuration would be needed for real-life usage.
