#	$NetBSD: Makefile.bootcd,v 1.44 2020/10/11 14:10:04 jmcneill Exp $
#
# Makefile snipped to create a CD/DVD ISO
#

# XXX TODO:
# 1) merge with src/distrib/cdrom
# 2) teach makefs to add data from more than 1 directory (see below)

#
# Required variables:
#	CDBASE		Basename of the iso
#
# Optional variables:
#	CDRELEASE	Set to 'true' to include $RELEASEDIR/$RELEASEMACHINEDIR on the CD
#	CDRELEASE_NOISOS Excludes installation/cdrom directory if set
#	CDRELEASE_NODEBUG	Excludes debug sets if set
#	CDSOURCE	Set to 'true' to include $RELEASEDIR/source on the CD
#	CDEXTRA		Set to a list of files or directories containing extra
#			stuff to put on CD (set by build.sh -C flag)
#	CDBUILDEXTRA	Set to a list of files or directories containing extra
#			stuff to put on CD (use in Makefiles)
#	CDEXTRA_SKIP	A list of file exclusion paths to exclude when copying
#			directories of extra stuff in CDEXTRA AND CDBUILDEXTRA
#	CDDEV_POPULATE	Set to 'true' to fully populate /dev on the CD (and
#			safe a tmpfs union mount)
#	BOOT		Defaults to $DESTDIR/usr/mdec/boot
#	BOOTXX_CD9660	Defaults to $DESTDIR/usr/mdec/bootxx_cd9660
#	CDBOOTOPTIONS	Options for installboot, eg -o console=com0,speed=9600
#	CDMAKEFSOPTIONS	Options for makefs, eg bootimage=i386;bootxx,no-emul-boot
#	CDMAKEFSEXTRAOPTS additional options for makefs, e.g. -F specfile
#	CDROMS_RELEASEDIR Where to install ${CDBASE}.iso
#	CDINSTKERNEL	instkernel directory (relative to ${.CURDIR})
#	CDKERNELS	couples of the form:
#				source	name_on_cd
#	CDRUNTIME	files/directories to copy from $DESTDIR onto the CD
#	CD_SETS		sets to be extracted onto the CD
#	SETS_DIR	where the CD_SETS are found (default provided)
# source kernels are copied from ${CDINSTKERNEL} (or its obj dir)
# note that as of yet, bootxx_cd9660 can't load kernel names of more than
# 8 chars (though they can be in a sub-directory meaning the pathname is
# longer than 8 chars)
