A couple additional thoughts about the boot-directdisk class in general:

So build_boot_dd needs a careful audit to ensure the various dd commands do not
stomp on eachother iirc, the dd of syslinux/mbr.bin was stomping on the
partition table or some such.

Also note that it uses "mkdosfs -d" which we have purged (and it aint coming
back if my NACK is worth anything ;-). Sounds like we need to abstract building
msdos images into an msdosfs.bbclass. No reason to duplicate all the fatfs
overhead calculations I did yesterday (See the patch I sent yesterday to
bootimg.bbclass).
