Jeff Roberson has committed soft-updates journalling to 9-CURRENT! It enables a small file system journal which works in combination with soft-updates to eliminate boot fsck's. It is different from most other implementations of file system journalling in that it doesn't journal raw blocks but sort of meta-data about meta-data (hyper-data?).

UFS journalling committed
Jeff Roberson has committed soft-updates journalling to 9-CURRENT! It enables a small file system journal which works in combination with soft-updates to eliminate boot fsck's.

SoftUpdates – the next generation (or SU+J)
Jeff Roberson is working on an addition to UFS softupdates which includes a tiny journal to keep track of things like free space and inode orphaning that were left to background fsck to deal with in the original implementation of softupdates. Basically, it's still the same old softupdates but without the need for (bg)fsck to be run for recovery!
