The test complains[1][2] that Failed to start message bus: Failed to bind socket "/run/dbus/system_bus_socket": No such file or directory In 639e5401ff51d4c0075b5ceffcbdbfec64c67db3, the dbus socket dir is set to `/run/dbus`; in the test vm `/var/run/dbus` is used, but the standard `/run -> /var/run` link is typically not created until stage 2 init, not in the minimal init used here. Thus, dbus fails to run within the test environment . Fix by changing `/var/run/dbus` to simply `/run/dbus`. [1]: https://hydra.nixos.org/build/42534725 [2]: https://hydra.nixos.org/build/42523834
