Title: Upgrade Systemd to v209

This is a pretty major change which brings dbus and systemd up to the most recent versions. I'm still working on this patch but I'd like to put it out there to make progress. Nixos still does not build even though systemd should.

One of the benefits to upgrading is that it would greatly reduce the complexity in our networking services as this version of systemd brings the networkd component.

Note: This looks to be broken on arm as per the release notes.
