A suggestion upstream was to use the uuid of the root filesystem. I'm
not sure things can happen in the right order for that, but I can give
that a shot.

If you're going to have to do that anyway, can you use the root fs uuid?
Would that supplant the need for this qemu patch?

You said our end-users need this. Historically are all of the people
who will need this using either libvirt or testdrive? Can we simply
hack testdrive to do this for us?
