Power can and will fail. Even with a UPS. :-(

In reading this thread, it sounds like FFS is the preferred FS for avoiding
data loss on *BSD. I only recall losing data once in many years with
NetBSD's FFS, a great improvement over previous BSD based systems.
If one is forced to run Linux :-( which FS is the least likely
to lose data, and how much worse is it than NetBSD's FFS?
