-obsolete wrapper around <link

+<para>The command <command>nix-collect-garbage</command> is mostly an
+alias of <link linkend="rsec-nix-store-gc"><command>nix-store
+--gc</command></link>, that is, it deletes all unreachable paths in
+the Nix store to clean up your system.  However, it provides an
+additional option <option>-d</option> (<option>--delete-old</option>)
+that deletes all old generations of all profiles in
+<filename>/nix/var/nix/profiles</filename> by invoking
+<literal>nix-env --delete-generations old</literal> on all profiles.
+Of course, this makes rollbacks to previous configurations
+impossible.</para>
