I don't expect a lot of gain from switching from aufs to btrfs as long
as we a have a single layer of snapshot (template -> ephemeral
instance). It will truly shines if/when we have more layers (template ->
{image-builder, test runner, any component with added deps really) ->
ephemeral instances).

The bakery stuff is really the key to avoid re-installing the same
packages again and again (i.e. the templates are good for a given day or
even a week).
