I've recently become very interested in the Hurd. I'd like to try it without creating a new partition on my drive, though. So, I created a 200 meg file and ran mke2fs on it. I then mounted it and ran the cross-install script, so I now have a Hurd disk image ready to boot. I'm assuming I can just use dd and write this to a disk partition if I like what I see. :) So, is it possible using GRUB to boot the Hurd from a file within an ext2 partition?
