# 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 (after the symbols are stored in
#			${FILENAME}.symbols.gz), and gzipped into
#			${FILENAME}.gz.
#
#			If KERNEL does not contain a `/', use
#			${KERNOBJDIR}/KERNEL/netbsd as the kernel.
#
#			If FILENAME is "-", use "netbsd-${KERNEL}" as
#			the target name.  This may not be a sensible
#			name if KERNEL contains a `/'.
#
# Optional variables:
#	MDSET_RELEASEDIR		Where to install release kernels.
#
#	MDSET_NOSTRIP.${FILENAME}	If defined, don't strip ${FILENAME}
#
#	MDSET_NOSYMBOLS.${FILENAME}	If defined, don't generate
#					${FILENAME}.symbols.gz
#
#	MDSET_POST.${FILENAME}		For each kernel named ${FILENAME},
#					execute this after ${NM} / ${STRIP}.
#					Kernel is available as "${.TARGET}"
#
#	MDSET_SUFFIXES.${FILENAME}	List of extra install kernel suffixes
#					and build commands to create from
#					${FILENAME} after its created by
#					${MDSET} ; ${NM} ; ${STRIP}:
#						SUFFIX	COMMANDVAR
#					"${.TARGET}" is "${FILENAME}.${SUFFIX}"
#					COMMANDVAR is the name of the variable
#					containing the command to build
#					${.TARGET}.
#
# Variables modified by this:
#	KERNELS			List of kernel .gz files to build
#	KERNELSYMS		List of kernel .symbol.gz files to build
