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

#
# Required variables:
#	NETBSDSRCDIR	Top level of src tree (set by <bsd.own.mk>)
#	MDSETTARGETS	List of images to ${MDSETIMAGE} into kernels,
#			containing one or more tuples of the form:
#				KERNEL	IMAGE	FILENAME
#
#			The kernel is ${MDSETIMAGE} with ${IMAGE},
#			${STRIP}ped (with the symbols are stored in
#			${FILENAME}.symbols.gz), and gzipped into
#			${FILENAME}.gz.
#
#			If FILENAME is "-", use "netbsd.${KERNEL}" as
#			the target name.
#
# Optional variables:
#	MDSET_RELEASEDIR		Where to install release kernels.
#
#	MDSET.${FILENAME}.post		For each kernel named ${FILENAME},
#					execute this after ${NM} / ${STRIP}.
#					Kernel is available as "${.TARGET:R}"
#					If MDSET.${FILENAME}.suffixes uses
#					this to build extra kernels, the
#					resultant file must be gzipped by this
#					as "${.TARGET:R}.${suffix}.gz"
#
#	MDSET.${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}
#
