Couple of misconceptions here. 1. A fsck on a rw mounted filesystem does not give ANY useful information. You can have both false positives and false negatives. 2. FFS didn't originate form FreeBSD. It was originally released in BSD 4.2, and further development continued --until this day-- in all BSD derivatives. Of course major work has been done by McCusick in FreeBSD. On a side note, background fsck isn't exactly the holy grail. See for eample http://lists.freebsd.org/pipermail/freebsd-fs/2010-July/008955.html Even McKusick says that isn't enough to depend on it, and a regular fsck is needed afterwards. Note the background fscks are only run on filesystems that were unclean on boot. -Otto
