boot0cfg -s doesn't set the active flag on partitions. It
changes some magic offset in the boot code that is being
interpreted by the boot code.

There's no equivalent to the -s option, because gpart doesn't
interpret or understand the boot code. You can change the
active partition with gpart though:

	# gpart set -a active -i <slice> ad0
