I’ve set up syncthing on my YunoHost box. I already had it on my desktop and my mobile. The whole point of Syncthing is kind of that it’s P2P, without a central server, but I thought this might be handy as an extra node for those two to sync between. I do occassionally get sync conflicts when I’ve edited stuff on both while they weren’t in communication with each other. It’s not a central server, just a more available node, I guess.
