> It would be awesome if the extensive command lines were shorted by being able to specify a configuration file instead of command line arguments.  A couple wishlist style things:
>   * command line flags override configuration file options
>   * ability to specify a sequence of configuration files to facilitate rolling out a new feature and having backup configurations if the config file contains incompatible information
>   * Possibly a stored configuration within the meta directory, and a way to update this configuration for non-impacting changes.  Possibly using the stored/check-pointed configuration as a fall-back if it would be task affecting.
> Pie in the sky:
>   * have the slave generate inverse offers and manage transitioning to new configurations.  Possibly by including a method to tell the environment how else to mitigate (please reboot host, kernel is incompatible, etc).
