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