This is great, I will definitely try it out in emacs. We use systemd unit files for quite a few things. During holidays I'm planning to uprade my setup to use more lsp and llm! Thanks!

I run a self hosted server of Squeezebox and have 10+ players around the house. The hardware is long discontinued, but can be bought second hand. I can stream Spotify and internet radio. Very happy with it. Connect the Squeezebox Touch via toslink to active speakers etc.

I run a squeezebox server, but with raspberry pi clients running squeezelite.

Add a hifi-berry card for optical or phono out, and connect to the amp in each room.

Also I have a pi which I can connect with cable to a Bluetooth speaker and power it with an Anker battery - take that out into the garden on a nice day. Takes multiroom to a new level :-)

What I am missing in cockpit, is a way to manage user services. Like a webinterface for "systemctl --user status" etc.

It does exists, though you can only manage services from the user that you login with afaik.
