I didn't even know that background fsck was supported at all.  I
remember hearing Kirk talk about it as a future feature at FreeBSD CON
last year, but I havn't heard anything about it since.  How do you
use it?


p.s.  Forgive me if this is well documented in -CURRENT.  At the moment,
the latest version of FreeBSD that I have available to me is 4.1-RC
(cvsup from July 21) and I can't find any mention of it.
