@url{http://nixos.org/nix/, Nix} replaces the three dependencies above.
+Guix is compatible with Nix, so it is possible to share the same store
+between both. To do so, you must pass @command{configure} not only the
+same @code{--with-store-dir} value, but also the same
+@code{--localstatedir} value (the latter is essential because it
+specifies where the database that store meta-data about the store is
+located, among other things.) The default values are
+@code{--with-store-dir=/nix/store} and @code{--localstatedir=/nix/var}.
+Note that @code{--disable-daemon} is orthogonal and is not required if
+your goal is to share the same store as Nix.
