Isn't the first question "how do I create an image?" :)

It's all in projects/fedora-xo in git, xo-1.5 branch. Makefile shows you
how we make builds including all the outputs. You'll need to get the
actual zhashfs tool from bios-crypto (also a git repo). Sorry that the
build system is a bit messy and undocumented, I hope to find time to
clean it up soon.
