All my airport signs run Arch, BTW.

Right, the thing that caught my eye was running a full desktop OS for a sign board.

Thanks for all of the suggestions. I’ll definitely look into these.

Thanks for the recc. I’ve used syncthing for syncing my phone with my PC and it works great. Though sync is not quite what I want since any file deletions on the PC get propagated to the folder on the server. Though maybe there is a way to change this behavior in syncthing?

Never heard of of Kopia. Will check it out.
