I found out that qemu will run from an ext2 filesystem image. Which is
neat I guess, however it is still rather difficult sometimes to work in
this manner. What would be really great for my setup would be to have
qemu use a chrooted directory. No image mess, it can write wherever it
wants, and when it isn't working, so can I. Once it is all setup, image
it and add your kernel and be done with it. Using the ext2 filesystem
image is pretty good though.
