System files are moved to `/etc/coreos-home-server` to be unambiguous
in relation to other, pre-installed system files. Long-running services
are also now defined as `Type=notify`, which helps improve ordering and
dependencies.
This commit represents a large amount of work toward moving services to
a more standard approach to storing data, and a simplification in how
networks are managed.
This will help make subsequent synchronization with hosts easier, as
systemd files and potential dropins are guarnateed to exist under a
certain hierarchy that can be dropped as-is into host configuration
directories.
