Maybe we're just being too fancy here.
We could rewrite -kernel/-append/-initrd to just generate a floppy
image in RAM, and just boot from floppy.
May be. Can floppy be 100M?
Well, in theory you can have 16384 bytes/sector, 256 tracks, 255
sectors, 2 heads... that makes 2^(14+8+8+1) = 2 GB. :) Not sure the
BIOS would read such a beast, or SYSLINUX.
By the way, if libguestfs insists for an initrd rather than a CDROM
image, it could do something in between and make an ISO image with
ISOLINUX and the required kernel/initrd pair.
(By the way, a network installation image for a typical distribution has
a 120M initrd, so it's not just libguestfs. It is very useful to pass
the network installation images directly to qemu via -kernel/-initrd).
