Hello, OP.
I’m currently using Orange PI 3 LTS as my home server and this thing is even less commonly known and less supported than Raspberry. I have spent couple of days trying to make Arch ARM work on this board but at the end I gave up and installed Manjaro ARM which is basically Arch with some of stuff preinstalled (but not too much in the minimal edition).
It was super easy to install and run, and now I happily use my Orange PI with Arch-based distro. Maybe you also can give it a try
Is it possible to change lemmy's domain after I have already started it once and produced some content? I am thinking of moving to a subdomain but I'm not sure if it will go smoothly
I see. Thank you for such a detailed explanation :)
