When GDM launches a new session it will inherit the user's systemd environment (but only unset variables). If `__NIXOS_SET_ENVIRONMENT_DONE` is set in the user's systemd environment it will prevent the environment to be set properly or updated (eg. after having done a system rebuild). Gnome sessions exports their environment to systemd at startup. If something is keeping the user's systemd process alive (eg. ssh) launching a new gnome session after logging out will result in a broken PATH. Specifically the PATH will be inherited from GDM and never reset. We patch GDM to never inherit `__NIXOS_SET_ENVIRONMENT_DONE` so new sessions will always reset their base environment. fixes https://github.com/NixOS/nixpkgs/issues/48255 For more info about the environment setup: https://github.com/NixOS/nixpkgs/pull/45784
