Help installing on a Raspberry Pi 3

If you install Java 8, it’s what MineOS will use. I don’t have instructions for how you’d install it on arch, but the key points are:

  1. Prefer 32 bit to 64 bit; 64 bit offers literally zero advantages to RPIs.
  2. Log in as the mc user (or whatever non-root user you’re using) and type in java -version. If it says Java 8, MineOS will use Java 8.
  3. Download the ARM version, preferably “hard-float”

Follow the supervisord instructions here if you use supervisor for starting the webui.
