Nice, #selfhosting https://lyrion.org/ just revived our old #Squeezebox! On :nixos: #NixOS it was just:
services.slimserver.enable = true;
# (plus opening TCP port 9000 and TCP/UDP 3484)
Then performing the setup wizard via http://localhost:9000 (only works via localhost, can also use an ssh port forward for example), then the Squeezebox listed the server on its own everything worked after selecting it. 👍
