# Makefile to create a bootable FS image for USB flash or emulators
#
#
# Required variables:
# RELEASEDIR
# Should be defined in nbmake-${MACHINE}
# IMGBASE
# Basename of the image
#
# Optional variables:
# BOOTDISK
# device name of target bootable disk specified in /etc/fstab
# (default: sd0)
# USE_MBR
# set yes if target disk image requires MBR partition
# (default: no)
# MBR_BOOTCODE
# optional MBR bootcode which should be installed by fdisk(8)
# (default: empty)
# - specified MBR_BOOTCODE must exist in ${DESTDIR}/usr/mdec
# - if MBR_BOOTCODE is not specified,
# MBR_DEFAULT_BOOTCODE (default: mbr) will be used
# if the target ${MACHINE} has the one in /usr/mdec
# USE_SUNLABEL
# set yes if target disk image requires Sun's label
# (default: no)
# INSTALLBOOT_AFTER_DISKLABEL (untested)
# set yes if the target ${MACHINE} requires disklabel
# to run installboot(8), like hp300
# (default: empty)
# IMAGEMB
# target image size in MB
# (default: 2048)
# SWAPMB
# swap size in target image in MB
# (default: 128)
# KERN_SET
# kernel set name which should be extracted into image
# (default: kern-GENERIC)
# SETS
# binary sets that should be extracted into image
# (default: modules base etc comp games man misc tests text
# xbase xcomp xetc xfont xserver)
# SETS_DIR
# directory path where binary sets are stored
# (default: ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets)
# IMGFILE_EXTRA
# list of additional files to be copied into images,
# containing one or more tuples of the form:
# FILE TARGETPATH
# for installation image etc.
# (default: empty)
# IMGDIR_EXTRA
# list of additional directories to be copied into images,
# containing one or more tuples of the form:
# DIR TARGETPATH
# for installation image etc.
# (default: empty)
# XXX: currently permissions in IMGDIR_EXTRA are not handled
# IMGDIR_EXCLUDE
# pax(1) options to exclude files which should not copied
# into TARGETPATH in IMGDIR_EXTRA
# (default: empty)
# FSTAB_IN
# template file of /etc/fstab
# (default: ${DISTRIBDIR}/common/bootimage/fstab.in)
# SPEC_IN
# default files of spec file for makefs(8)
# (default: ${DISTRIBDIR}/common/bootimage/spec.in)
# SPEC_EXTRA
# additional files of spec file for makefs(8)
# (default: empty)
# IMGMAKEFSOPTIONS
# options passed to makefs(8) to create root file system
# (default: -o bsize=16384,fsize=2048,density=8192)
# INSTALLBOOTOPTIONS
# options passed to installboot(8), e.g., -o console=com0
# (default: empty)
# PRIMARY_BOOT
# primary boot loader that should be installed into
# the target image via installboot(8)
# (default: empty)
# SECONDARY_BOOT
# secondary bootloader that should be put into the target image
# (default: empty)
# SECONDARY_BOOT_ARG
# extra arguments that should be passed to installboot(8)
# to specify the secondary bootloader
# (default: empty)
# DISKPROTO_IN
# template file of disklabel -R
# (default: ${DISTRIBDIR}/common/bootimage/diskproto.in
# or ${DISTRIBDIR}/common/bootimage/diskproto.mbr.in)
# OMIT_SWAPIMG
# no need to put swap partition into image (for USB stick)
# (default: no)
