Yes, but this happens in absense of real user data or configuration.
Which means that all those fancy conditionals ("are we upgrading from
an earlier version? update the format in which we store the data!")
are skipped. The need for those scripts is somewhat lower on our
platform so far, but without them there is a whole lot of stuff we
cannot deal with gracefully.
