# 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)
