You probably have the various filesystems for Linux in mind.  The
situation is different for BSD (which isn't necessarily a bad thing).
The Berkeley Fast File System (FFS, sometimes referred to as UFS) is the
standard filesystem on BSD.

Apart from the FFS docs already mentioned, you might want to have a look
at the paper on soft updates for FFS:

The following paper compares soft updates and journaling filesystems:
