# Creates a bootable image using syslinux, your kernel and an optional
# initrd
#
# End result is two things:
#
# 1. A .hddimage file which is an msdos filesystem containing syslinux, a kernel,
# an initrd and a rootfs image. These can be written to harddisks directly and
# also booted on USB flash disks (write them there with dd).
#
# 2. A CD .iso image
# Boot process is that the initrd will boot and process which label was selected
# in syslinux. Actions based on the label are then performed (e.g. installing to
# an hdd)
# External variables
# ${INITRD} - indicates a filesystem image to use as an initrd (optional)
# ${ROOTFS} - indicates a filesystem image to include as the root filesystem (optional)
# ${AUTO_SYSLINUXCFG} - set this to 1 to enable creating an automatic config
# ${LABELS} - a list of targets for the automatic config
# ${APPEND} - an override list of append strings for each label
# ${SYSLINUX_OPTS} - additional options to add to the syslinux file ';' delimited
