Re: Submodules implementation

I see that in the submodule there is a .git directory with its own objects.  
This does not look like as if the submodule objects are part of the 
superproject.

Because they largely aren't.  submodules are freestanding projects on
their own right.

One of the primary design decisions was to support the use of a
superproject without having to clone/checkout all the submodules.

You may want to check earlier design discussion thread:

  http://thread.gmane.org/gmane.comp.version-control.git/31941/focus=32944

It is a huge thread and some of the messages there might be nothing more
than uninformed and unworkable handwaving, except for the ones from Linus
and some others.
