OpenBSD uses soft updates.  That just makes fsck able to fix almost any problem, but you still have to wait for FSCK!!!!

check out this interview with Theo de Raadt(http://kerneltrap.com/article.php?sid=389).  About a quarter of the way down he talks about file systems and why soft updates are better than journaling FS....

I would prefer to give up the performance and have journaling than to wait for FSCK.  Plus my firewall is headless, so when it comes down (say from a power failure! YES I NEED A UPS) it sometime wants me to boot into single user mode and manually run FSCK.  There is no keyboard, monitor, or even video card, so that becomes a pain in the arse!
