Since the _frigate.service_ unit depends on _dev-apex_0.device_,
`/dev/apex_0` needs to have the `systemd` "tag" on its udev device info.
Without this tag, systemd will not "see" the device and thus will not
mark the `.device` unit as active.
Frigate has evolved a lot over the past year or so since v0.13.
Notably, some of the configuration options have been renamed, and
_events_ have become _alerts_ and _detections_. There's also now
support for authenication, though we don't need it because we're using
Authelia.
* Switch to Quadlet-style `.container` for systemd unit
* Update to new image tag naming scheme (not arch-specific)
* Use environment variables for secrets
* Allow the entire `frigate_config` variable to be overridden
Frigate is an NVR that uses machine learning to detect objects on camera
in real time. It integrates with Home Assistant to expose sensors which
can be used for automation, etc.
The only official way to deploy Frigate is with a container, so we use
Podman and systemd to manage it.
