    Is there a cramfs based checksum on the data that is being stored on the MTD where the cramfs mounts ? Say, there is some data on MTD device 2 and the kernel

      Is there a cramfs based checksum on the data that is being stored on
      the MTD where the cramfs mounts ? Say, there is some data on MTD
      device 2 and the kernel mounts the cramfs image on MTD device 2 and is
      there any mechanism to verify that the data on the cramfs image hasn't
      been compromised?

      I guess JFFS2 also has it's own checksum, because it detects bad
      blocks. Correct me if I'm wrong.

      thanks
