- Move HyperKit code into a separate file. It should be compilable on all supported OSes now. - Add a (optional) subcommand to "moby run" to select a backend i.e., "moby run hyperkit [options] [prefix]" - On macOS the default is "hyperkit" so that: "moby run [options] [prefix]" just works - Add enough command line parsing to make it easy to add new backends to the run command Update help messages.
