+      Disable all automatic updates, including:

+        - Extensions

+      If some or all of these are externally managed, we may want to prevent automatic
+      updates from undoing our changes.
+
+      If any properties of our deployment have been audited, automatic updates may introduce
+      unaudited components and compromise any guarantees made about the users security or privacy.
