That's the thing: nothing did.  So why run fsck at all?

Oh, you're thinking of using fsck for recovery purposes.
That's a different situation.  I was just talking about the idea of "not
needing to do fsck any more", which is pretty much already the case for
XFS and ext3, AFAIK.

Actually I call it "router" because it was sold as such and it replaced
a machine which I originally used as such as well.  Really it's just
a small home server which stores&plays my music, stores my movies and
other such things, ...  It doesn't actually do any routing at all.
