    I have two image files that I've created with `makefs` and `mkimg`. When I attach them both to a bhyve instance and boot it for the first time, it fails to boot.

    When I boot with only the first image, and then boot a second time attaching the second image, then it boots but does not recognize the zpool in the second image.
    When I boot with only the first image, it boots correctly. I can then shut it down and boot a second time attaching the second image, and it boots but does not recognize the zpool in the second image.
