I guess. I don't know that the later is more clear. I think the source
of the confusion is the entire concept of "first bootable harddisk"
which is what -boot c really means.
FWIW, the reason media=cdrom,boot=on doesn't work, is that a CDROM's
boot record is in el torito format instead of the traditional BIOS boot
sector.
media=cdrom,boot=on would work if the image was a disk image instead of
an ISO.
In fact, I'm inclined to think that media=cdrom,boot=on should not be
explicitly prohibited because of this fact.
