Are OS images checked for integrity by the XO before they are written
to the flash storage? I suspect not.

The schools we deal with don't always have reliable Internet, so some
failsafe mechanism to prevent them from using damaged images would be
helpful. We can't expect them to learn md5sum to check the image first
- that is too technical.
