Puppy is great! I'm really impressed with how much is already working with
so little code.

I've built this and qemu-kvm-sheepdog to test and it seems to be running
well for me. I'm running with script/start-puppies -n=5 on a single host
which is obviously not too good for performance, but lets me try out things
like mkfs --copies=3 and watch what's going on on disk.

So far I've successfully created an image, booted a live CD in qemu, made a
filesystem on my image, and I'm just about to do a bit of general stress
testing on it.

Best wishes,
