+        bool "Make audit loginuid immutable"
+        depends on AUDIT
+        help
+          The config option toggles if a task setting it's loginuid requires
+          CAP_SYS_AUDITCONTROL or if that task should require no special permissions
+          but should instead only allow setting its loginuid if it was never
+          previously set.  On systems which use systemd or a similar central
+          process to restart login services this should be set to true.  On older
+          systems in which an admin would typically have to directly stop and
+          start processes this should be set to false.  Setting this to true allows
+          one to drop potentially dangerous capabilites from the login tasks,
+          but may not be backwards compatible with older init systems.
