This parameter can be used to the "make installkernel" command,
for example in a workflow like this:

	# make buildkernel KERNCONF=TESTKERNEL
	# make installkernel KERNCONF=TESTKERNEL KODIR=/boot/testkernel

Plus the corresponding settings in /boot/loader.conf:

	kernel="testkernel"
	bootfile="/boot/testkernel/kernel"
	kernel_options="foo bar blah"

See /boot/defaults/loader.conf for details.

For booting test kernels, you might also find the nextboot command
very helpful; read "man nextboot" for more inspiration.
