    Experimental support for Sid's checkpointer. · e753d3e9

    The checkpoint driver can return a list of blocks that have been modified
    since its startup.  If you use "imagezip -C /dev/shd0 -s 1 /dev/ad0 foo.ndz"
    imagezip will make an ioctl call on the shd device to get the modified
    blocks it needs to save (rather than parsing the filesystem).  It then
    creates an image using those blocks.
    
    The end result should be an "incremental" image that can be put down on
    the disk by frisbee after the original image has been loaded.
    
    This is all a theory right now (including the ioctl :-) but should get
    tested RSN.
