Unfortunately, no. :-(

There have been problems, and they've been corrected quickly. However, a
new one just cropped up this morning (see "File corruption causing
SVNadmin seg fault", msgid

Don't get me wrong, FSFS has proven to be stable thus far... but it's also
relatively new. The reason that we may not be seeing as many problems is
because it just isn't used as much, and it's operating fine in whatever
conditions it happens to be in. *shrug* All of this is really just
speculation anyways, unless we find a way to get more solid numbers about
the installed user base.
FWIW, I've been using BDB for years now, and I've had no corruptions, no
dataloss, and I've only had to 'svnadmin recover' a repository once...
and that was due to a problem in the way I set it up.
