    When using per-node kernel parameters, i.e. ``kernel_append_params`` in the
    node's ``instance_info`` or ``driver_info``, it is now possible to insert
    the value of the driver's configuration option (e.g.
    ``[pxe]kernel_append_params`` via the special ``%default%`` syntax, e.g.::

      baremetal node set node-0 \
        --driver-info kernel_append_params="%default% foo=bar"
