As discussed in the engineering meeting today, I believe the underlying
issue is that the filesystem is being mounted read-write, and I can see from
your diff that this is explicitly the case.
By changing the appropriate '-o rw' to '-o ro', you should be able to fix
this without changing to an ext3 filesystem.
