Soft updates are a crutch for a file system that was not designed to 
accommodate that type of behavior. The complexity added to the file 
system for the sake of one feature of having a shorter boot time under 
special circumstances is unreasonable.

Journaling has the potential to be, from the outset, a more flexible and 
robust design. That is, if I'm not mistaken, one of the primary goals of 
DragonFly.
