Rather than tweaking this horrible thing, what about using sfdisk
instead, or even better, switch to genimage to generate the image ? The
latter would really be the ideal solution (but I would accept a patch
changing to sfdisk in the mean time, if you don't have the time to look
into genimage right now).

Thanks!
