For me, the worst part of setting up some new distro or service is when it’s done and everything works. Then it just… Sits there. Working. Usually at some task I don’t need very often. Very anticlimactic and boring. Then I have to find some other new thing to try, which is why my HTPC has been through like 4 distros in the past year.
They should flash when they are first turned on, so you can tell that they turned on. That helps diagnose connection issues versus power issues. After that, though, darkness please.
