Sorry, but I have to disagree. The filesystem that FreeBSD uses (UFS to some, FFS to others) has a feature known as 'snapshots', something alien to people in the Linux world. What this means, is that one can take a 'snapshot' of a drive's state (somewhat like a versioning tag), and mount, dump, OR fsck it. The point of a background fsck is that the SNAPSHOT is fsck'd, and only if there is a problem (which there usually isn't, due to soft-updates meaning that data are rarely lost on power loss) does fsck require write access to the volume in question. This is also why you can dump a live filesystem in FreeBSD. Just to reiterate something said a thousand times, there is NOTHING WRONG with background fscks, and just because something doesn't work well for GNU/Linux doesn't mean it doesn't work with FreeBSD. There are many differences, after all. Chris -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.
