# 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}"
#
# Optional variables:
#	MDSETDIR		where to install kernels with "release" target
#	${FILENAME}.post	run after ${STRIP}; kernel is netbsd.tmp
#
# Variables modified by this:
#	KERNELS			List of kernel .gz files to build
#	KERNELSYMS		List of kernel .symbol files to build
#	_KERNEL.${KERNEL}	Target filename for ${KERNEL}
#
