yes.

you can check here:

https://github.com/lxc/lxd/blob/master/doc/storage-backends.md#feature-comparison

in resume, between btrfs and zfs almost no difference.

I use btrfs three times, the first and third time without problems and 
the second time "almost" without problem.

You can see here:

that sometimes you will have problems with trusty/utopic if you do a 
dirty reboot. This was my problem when i was in trusty with 3.14 kernel 
and btrfs from this version. And they recommend upgrade at least to 
vivid with upraded btrfs in kernel and upgraded btrfs-tools.

some weeks ago i use trusty but with xenial kernel from hwe (4.4.x) and 
btrfs-tools from lxc stable ppa 
(https://launchpad.net/~ubuntu-lxc/+archive/ubuntu/stable).

I am waiting some weeks to install xenial and lxd ... over btrfs for 
desktop and servers.
