Turning Raspberry Pi into Jellyfin Media Player Box?

https://lemmy.ml/post/1728887

I found the DietPi OS to be great for getting a media server going. Alternatively, just install a lightweight OS, install docker, then set up Sonarr / Radarr / Prowlar / Overseerr (or Jellyseerr) / a torrent client / Jellyfin using docker. Make sure you transfer the OS off the memory card though, they eventually corrupt if you run the OS off them. Not sure about a remote, Plex let’s you use the android app to fling media to another Plex app on the same network, maybe Jellyfin has similar?
If I’m not mistaken, this post isn’t asking about setting up a separate server instance, but setting up a Pi as a dedicated client for OP’s friend to access OP’s server.
Precisely. I made an edit earlier to clear that up.
