    image: use du --apparent-size when calculating rootfs size
    
    We should pass --apparent-size to du when calculating how large the rootfs is as
    otherwise we get the actual disk usage, which if the files are compressed by the
    file system (such as ZFS) may be sufficiently smaller than the space required by
    the image that construction will fail.
