So I've been researching, because I thought this "Soft Update" thing
that BSD uses was some weird freak-ass way to totally corrupt a file
system if the power drops.  Seems I was wrong; it's actually just the
opposite, an alternate solution to journaling.  So let's compare notes.

I hate to say it...but in my experience, this has been exactly the case with soft updates and FreeBSD 4 up to 4.11 pre releases.

Whenever something untoward would happen, the filesystem almost always lost files and/or data, usually just files though. In practice it's never really worked too well for me. It also still requires a full fsck on boot, which means long boot times for recovery on large filesystems.
