+  <listitem>
+    <para>Nix no longer sets the immutable bit on files in the Nix
+    store.  Instead, the recommended way to guard the Nix store
+    against accidental modification is to make it a read-only bind
+    mount, like this:
+
+<screen>
+$ mount --bind /nix/store /nix/store
+$ mount -o remount,ro,bind /nix/store
+</screen>
+
+    Nix will automatically make <filename>/nix/store</filename>
+    writable as needed (using a private mount namespace) to allow
+    modifications.</para>
