Hi,
I already have told about that in a comment here <http://git-annex.branchable.com/bugs/submodule_path_problem/#comment-e86330d15b714a41a07b6548fbc79bb2>, but I am not sure it will be seen.

Then here is an official bug report.
### Please describe the problem.

I have a problem with submodules when the git repository is not a submodule everywhere.

For instance, if A is a git annexed repository and B another git repository. If B adds A as submodules. The symlinks added in A as submodule won't work in the original A.

### What steps will reproduce the problem?

    # creating the master repository
    mkdir annex_master
    cd annex_master/
    git init
    # hack: adding a file to create the master branch
    touch start
    git add start
    git commit -m "start"
    cd ..
    # create another repository
    mkdir annex_sub
    cd annex_sub/
    git init
    # hack: adding a file to create the master branch
    touch start
    git add start
    git commit -m "start"
    # it is a annexed repository
    git annex init sub
    # add the other repository as submodule of the master one
    cd ../annex_master/
    git submodule add ../annex_sub/ module
    cd module/
    git annex init sub_module
    git annex sync origin
    # add an annexed file
    echo test > test
    git annex add
    git annex sync
    # go back to the origin repository
    cd ../../annex_sub/
    git annex sync
    ls -l
This returns test -> ../.git/modules/module/annex/objects/w8/pv/SHA256E-s5--f2ca1bb6c7e907d06dafe4687e579fce76b37e4e93b7605022da52e6ccc26fd2/SHA256E-s5--f2ca1bb6c7e907d06dafe4687e579fce76b37e4e93b7605022da52e6ccc26fd2

Actually, the file committed is correct. But the fact it points to '../.git/modules/module/...' makes the link work only if the repository is also a submodule and if this submodule is also located in the modules folder in the parent git repository.

I tried playing with making the repository direct and then indirect, hoping that would fix the symlinks, but it did not work.
