kernel selection menu to the beastie menu. List of kernels is taken from `kernels' in loader.conf(5) as a space (or comma) separated list of names to display (up to 9). If not set, default value is "kernel kernel.old". Does not validate that kernels exist because the next enhancement will be to allow selection of the root device.
