The answer to How to start and use ssh-agent as systemd service? gets us a running ssh-agent. How can you write another systemd service file so that its process runs under that ssh-agent? In particular I want to run an emacs service so that I can edit remote files using tramp.
This service file starts emacs but it's not running under ssh-agent.
