+     For that to work, the gvfs nixos service is enabled by default,
+     and it can be configured with the specific package that provides
+     GVfs. Until now Xfce4 was setting it to use a lighter version of
+     GVfs (without support for samba). To avoid conflicts with other
+     desktop environments this setting has been dropped. Users that
+     still want it should add the following to their system
+     configuration:
+     <programlisting>
+<xref linkend="opt-services.gvfs.package" /> = pkgs.gvfs.override { samba = null; };
