Osmscout-server includes a setting in its UI to create a systemd user service and socket to run the server on demand. This does not function correctly on NixOS, for two reasons: 1. It assumes that the binary path is stable (e.g. /usr/bin/osmscout-server), which is not the case on NixOS. 2. It auto-detects the unwrapped binary path, which doesn't work. This module allows the user to access the same functionality on NixOS.
