[description]
While using a 16.04 (Xenial) lxd cloud image, trying to setup lxd backed by zfs fails to create due to a missing /dev/zfs

[cloud-config]
#cloud-config
lxd:
  init:
    storage_backend: zfs
    storage_pool: lxd

[steps to reproduce]
Image used: b9cba741ef62 ubuntu 16.04 LTS amd64 (release) (20161115)

lxc init ubuntu:xenial/amd64 xenial
lxc config set xenial user.user-data - < cloud-config.yaml
lxc start xenial

[actual result]

root@xenial-lxd:~# ls /dev/zfs

[expected result]
I would have expected zfs to be setup with a pool named 'lxd' and cloud-init to complete successfully.
