-.It Cd option FFS_SOFTUPDATES
-Enables a scheme that uses partial ordering of buffer cache operations
-to allow metadata updates in FFS to happen asynchronously, increasing write
-performance significantly.
-Normally, the FFS filesystem writes metadata updates synchronously which exacts

-With soft updates, the performance of asynchronous writes is gained while
-retaining the safety of synchronous metadata updates.

-Soft updates must be enabled on a per-filesystem basis.
