Well I do not know if it is less robust, but I can tell I managed to
corrupt it to the point the root could not be mounted anymore.

FFSv2 does not use file as backing store, the attribute are said to be
"native". I suspect it is indeed more robust. I would be happy if
someone is ready to import that code.
