ext4 should work, but you'd be missing compression (activated in the
fs, not lxd-specific), quick container creation (with snapshot/clone,
managed my lxd directly), and container disk quota support. Those are
things that comes to mind immediately, there might be others.

I suggest you test the latest state yourself, either with latest 16.04
daily build, or 14.04 with relevant ppas.
