I tried the script on the kindle, it seems it works

[root@kindle root]# time ./copycmp.sh /dev/mmcblk0p2 /mnt/us/blk0p2.img

Now should I try to do something like this?

./copycmp.sh /mnt/us/rootfs.img /dev/mmcblk0p1

and check it with

./dc3dd if=/mnt/us/rootfs.img hof=/dev/mmcblk0p1 hash=sha1 ssz=4096 nwspc=on verb=on

correct?

I got some problem coping the rootfs.img with usb, the file copied had a different md5 hash, so I had to split in a bunch of chunks, copy them(one at time), and join them using the serial console
