I hope the announcement I just sent responded to this; but basically,
the toolkit works on a somewhat higher level (it uses zzuf, which I
believe to be similar to fsfuzzer but actually only fuzzes the
filesystem image and does not itself run tests on it; zzuf is not
written by me). Mostly the toolkit is about managing a virtual machine
to run tests automatically and about minimizing the differences to
pristine filesystems.

I confess I'm not intimately familiar with fsfuzzer (I should be!),
but I believe one of the advantages of berserker is that it automates
the virtual machine stuff and provides convenient scripts that can be
used with e.g. git bisect run.
