Creates separate snapper services for root and home directories. Does
_not_ yet set up any btrfs mounts or ensure that they are mounted at the
locations.
Can be used to have the ansible playbook run on the currently running
(host) machine, using a local connection instead of a chroot.
TODO: This _will_ change your host machine so be careful running this.
Additionally, we need to find a way to deduplicate the inventory
variables since we have them doubled for chroot/local now.
