# Makefile snippet to ${MDSETIMAGE} file system images into kernels
#

#
# Required variables:
#	_SRC_TOP_	Top level of src tree (set by <bsd.own.mk>)
#	MDSETTARGETS	List of images to ${MDSETIMAGE} into kernels:
#				KERNEL	IMAGE	FILENAME
#			The kernel ${KERNOBJDIR}/${KERNEL}/netbsd is
#			${MDSETIMAGE} with ${IMAGE}, ${STRIP}ped,
#			and gzipped into ${FILENAME}.gz.
#			If FILENAME is "-", use "netbsd.${KERNEL}" as
#			the target name.
#
# Optional variables:
#	MDSETDIR			Where to install release kernels.
#	MDSET.${FILENAME}.post		For each kernel named ${FILENAME},
#					execute this after ${NM} / ${STRIP}.
#					Kernel is available as netbsd.tmp.
#					If MDSET.${FILENAME}.suffixes uses
#					this to build extra kernels, the
#					resultant file must be gzipped as
#					"netbsd.${suffix}.gz"
#	MDSET.${FILENAME}.suffixes	List of extra install kernel suffixes.
#					The extra kernels are usually created
#					by MDSET.${FILENAME}.post.
#
# Variables modified by this:
#	KERNELS			List of kernel .gz files to build
#	KERNELSYMS		List of kernel .symbol files to build
#	_KERNEL.${KERNEL}	Target filename for ${KERNEL}
#
