In order to better support applications which use the new
rtems_task_construct() directive add the

The name CONFIGURE_INIT_TASK_STORAGE_SIZE does not reflect the role described
here and is a little ambiguous unless you know the implementation detail.
CONFIGURE_INIT_TASK_CONSTRUCT_STORAGE_SIZE ?
I am not sure. The storage size is a property of the task. How this property is
achieved is a detail and may change.
Is it a property of a specific instance (Init) of a specific type (construct) of
task?
You have stated:
"If this option is specified, then the Classic API initialization task
is constructed with rtems_task_construct()."
This is how I am reading this sentence. Sure in time the task may not be
constructed and that may change but the effect needs to be a "constructed" task
or you would need another variables.
The key issue is the config option triggers a change in the type of Init task
and we should be as clear about that as we can.
I changed the documentation of CONFIGURE_INIT_TASK_STORAGE_SIZE to not mention
rtems_task_construct(). This is just an implementation detail.
Does this mean all Init tasks will be statically constructed tasks?
No, if you specify CONFIGURE_INIT_TASK_STACK_SIZE (this is also the
default), then rtems_task_create() is used. If you specify
CONFIGURE_INIT_TASK_STORAGE_SIZE, then rtems_task_construct() is used.
For a user it should be no concern how the system creates the Classic
API initialization task. What matters is that the task has the
configured properties.
