Yes, I got that.  I think my concern is still valid, so probably I was
just unable to phrase it explicitly.  So I retry:

In the state above (i.e. linux-2.6 being a commit) the
superproject's odb doesn't necessarily needs the object
0123456789abcde0, right.  But the commit before that had linux-2.6 being
a tree.  And in that state linux-2.6/Makefile has to be in the
superproject's odb.  So if you choose the save the objects of submodules
in a different odb, linux-2.6/Makefile has to be in both of them.
 
I agree with the things you said afterwards, but they don't match the
issue I wanted to point out.

Best regards
Uwe
