Removal of the soft dependencies feature of the fast file system (FFS) was today completed by Andrew Doran. It was announced in a mail and discussed several times at the NetBSD mailing lists.
Soft dependencies will continue to be available in NetBSD 5.0. From 6.0 onwards the preferred method of maintaining integrity and achieving optimal performance with fast file systems is logging (WAPBL).
The file system format is upwards compatible: existing systems will continue to operate with no configuration changes, and migration to logging will be a simple matter of changing /etc/fstab.
