Exceptions would be things like dedicated database servers and such, where you have applications basically constructing their own file systems on top of the OS's file system. "Always"... Correct me if I'm wrong, but my understanding is if you are still using i386 (cheap/old hardware) without lots of RAM (1-2 GB) and large disks (3/4/5TB), zfs is not going to be a good choice.
