Your ssh/machines file always points to /etc/nix/docker_rsa when it tries to connect to the container, so your instructions for single user installations won't work. I have updated your README.md to always use the /etc/nix directory to keep the key for both types of installations.
I have also added an instruction to add/edit the builders directive in the nix config to point to your machines file found in /etc/nix.
