3# Makefile snippet to ${MDSETIMAGE} file system images into kernels
4#
5
6#
7# Required variables:
8#	NETBSDSRCDIR	Top level of src tree (set by <bsd.own.mk>)
9#	MDSETTARGETS	List of images to ${MDSETIMAGE} into kernels,
10#			containing one or more tuples of the form:
11#				KERNEL	IMAGE	FILENAME
12#
13#			The kernel is ${MDSETIMAGE} with ${IMAGE},
14#			${STRIP}ped (after the symbols are stored in
15#			${FILENAME}.symbols.gz), and gzipped into
16#			${FILENAME}.gz.
17#
18#			If FILENAME is "-", use "netbsd.${KERNEL}" as
19#			the target name.
20#
21# Optional variables:
22#	MDSET_RELEASEDIR		Where to install release kernels.
23#
24#	MDSET_NOSYMBOLS.${FILENAME}	If defined, don't generate
25#					${FILENAME}.symbols.gz
26#
27#	MDSET_POST.${FILENAME}		For each kernel named ${FILENAME},
28#					execute this after ${NM} / ${STRIP}.
29#					Kernel is available as "${.TARGET}"
30#
31#	MDSET_SUFFIXES.${FILENAME}	List of extra install kernel suffixes
32#					and build commands to create from
33#					${FILENAME} after its created by
34#					${MDSET} ; ${NM} ; ${STRIP}:
35#						SUFFIX	COMMANDVAR
36#					"${.TARGET}" is "${FILENAME}.${SUFFIX}"
37#					COMMANDVAR is the name of the variable
38#					containing the command to build
39#					${.TARGET}.
40#
41# Variables modified by this:
42#	KERNELS			List of kernel .gz files to build
43#	KERNELSYMS		List of kernel .symbol.gz files to build
44#
