As a counter example I installed void because it’s so well rated. They have a terminal only and UI build (xfce). I installed the UI build. On first boot, clean machine, clean drive, the UI wouldn’t load. I don’t like systemd much but it can load a window manager 🙄

For the curious, I did look for answers and basically the answer is debug runit scripts or try re-installing and see if that fixes it. Nothing concrete, but I’m also not alone in this bad experience.
