Setting `AutoUpdate=registry` will tell Podman to automatically fetch
an updated container image from its corresponding registry and restart
the container. The `podman-auto-update.timer` systemd unit needs to be
active for this to happen on a schedule.
`dest` is not a valid option for the `--mount` argument to `podman`. To
specify where the target path, only `target`, `destination`, and `dst`
are valid.
`upsmon` is the component of NUT that tracks the status of UPSs and
reacts to their changing by sending notifications and/or shutting down
the system. It is a networked application that can run on any system;
it can run on a different system than `upsd`, and indeed can run on
multiple systems simultaneously.
Each system that runs `upsmon` will need a username and password for
each UPS it will monitor. Using the CUE [function pattern][0], I've
made it pretty simple to declare the necessary values under
`nut.monitor`.
