+  The value of this configuration option defines the task storage size of the

+notes: |
+  If this configuration option is specified, then
+
+  * a task storage area of the specified size is statically allocated by
+    ``<rtems/confdefs.h>`` for the Classic API initialization task,
+
+  * the Classic API initialization task is constructed by
+    ${/rtems/task/if/construct:/name} instead of using
+    ${/rtems/task/if/create:/name},
+
+  * the maximum thread-local storage size defined by
+    ${max-thread-local-storage-size:/name} is used for the Classic API
+    initialization task,
+
+  * the Classic API initialization task should be accounted for in
+    ${min-tasks-with-user-provided-storage:/name}, and
+
+  * the task storage area used for the Classic API initialization task is not
+    reclaimed by the system if the task is deleted.
+
+  The
+
+  * ${init-task-stack-size:/name} and
+
+  * ``CONFIGURE_INIT_TASK_CONSTRUCT_STORAGE_SIZE``
+
+  configuration options are mutually exclusive.
