The `discord-ircd` service has been removed as of a few commits ago, but
references to this were not removed entirely. In addition, we now mask,
not disable, the `coreos-home-server-update` timer to ensure this cannot
be re-enabled spuriously.
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.
