    # This plugin implements NFS synced folders. In order to take advantage
    # of NFS synced folders, some provider-specific assistance is required.
    # Within the middleware sequences, some data must be put into the
    # environment state bag:
    #
    #   * `nfs_host_ip` (string) - The IP of the host machine that the NFS
    #     client in the machine should talk to.
    #   * `nfs_machine_ip` (string) - The IP of the guest machine that the NFS
    #     server should serve the folders to.
    #   * `nfs_valid_ids` (array of strings) - A list of IDs that are "valid"
    #     and should not be pruned. The synced folder implementation will
    #     regularly prune NFS exports of invalid IDs.
    #
    # If any of these variables are not set, an internal exception will be
    # raised.
