3# Makefile snippet to build a tree from the provided lists,
4# and make an ffs file system image from that tree
5#
6# Required variables:
7#	NETBSDSRCDIR	top level of src tree (set by <bsd.own.mk>)
8#	LISTS		list file(s) to use
9#	IMAGEDEPENDS	depends for ${IMAGE}
10#	IMAGEENDIAN	endianness of ${IMAGE}
11#	IMAGESIZE	size of ${IMAGE}
12#	MTREECONF	mtree specfiles to use to build a master specfile
13#
14# Optional variables:
15#	IMAGE		name of target image
16#	IMAGEPOSTBUILD	operation to run on ${IMAGE} ${.TARGET} after its built
17#			(if this returns non zero, ${.TARGET} is removed)
18#	CRUNCHBIN	name of crunchgen(1)ed binary
19#	DESTDIR		destination directory
20#	MAKEFS_FLAGS	extra options to ${TOOL_MAKEFS}
21#	PARSELISTENV	environment variables to set for parselist.awk
22#	WORKDIR		directory to build image in to 
23#	IMAGETAR	tar.gz file to create containing ${IMAGE}'s contents
24#
25#	IMAGE_RELEASEDIR	where to install ${IMAGE}.gz
26#	IMAGETAR_RELEASEDIR	where to install ${IMAGETAR}
