Yes, it should.  I've been trying to make sure that the bugs we know
about in b2 are documented in the BTS and fix them; the first part
should at least be done now.  I should also dig out my RFC mail on the

was what b2's "smooth updates" feature was designed for.  It's not
currently enabled as doing so would cause potentially significant
differences in the output between b1 and b2.
