As someone who just last night set up an Ubuntu 16.04 server with the intention of using ZFS, should I wait until this hits the Ubuntu repos? Is it possible to enable this encryption on an existing filesystem?
My zpool isn't very full. Maybe I can make a new dataset that's encrypted and move everything from the unencrypted dataset to the encrypted dataset. Of course, being able to encrypt in place would be most ideal, but I'll settle for it being a painless operation that doesn't require blowing away a zpool.
