-# Creates a bootable image using syslinux, your kernel and an optional

-#
-# End result is two things:
-#
-# 1. A .hddimg 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 (also used by syslinux.bbclass)
-# ${INITRD} - indicates a list of filesystem images to concatenate and use as an initrd (optional)
-# ${COMPRESSISO} - Transparent compress ISO, reduce size ~40% if set to 1

-# ${NOHDD}  - skip building the HDD image if set to 1
