The easy solution is putting the whole image in /dev/hda1 thought it
is theoretically possible to put the image on a filesystem and just
setup an ELF header at the start of the disk that points to it.
Etherboot also supports booting this way. And it will allow you to
multiplex between a hard drive and the network. So it is definitely a
good direction to look at.
