 Yes you are right but this trick works one time and the next? The
first run an embedded system has to overwrite a key BUT the next time
have to fails if key change, for example. I think overwrite the key
once time when nedded is safer than disabling host check and key
forever. For this reason I am attaching the patch again, hoping you
will applay it.
