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]

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