As Luzifer is some old HP ProBook that simply Prometheus' and Grafanas throughout the day, I need to make this build (see #3) up and running at every (re)boot.
Seems to work but there is an issue with the assumption I could comma-separate the URLs. Will require another ticket.
Located in the NixOS configuration for Luzifer as well as the Own NixPkgs and Own NixOS module training repositories.
