Re: Query on git submodules

What does this 10+ layers mean? Nested submodule repositories 10
recursion steps deep?

We have experience issues with re-use of design projects was we move
from one derivative to another due to the complexity of the hierarchy
along with lack of discipline (using absolute paths in .gitmodule
files). To enforce more discipline I am currently working on a
pre-commit hook to check the integrity of .gitmodule files.  I would be
interested in seeing how other users in the community find submodules
for large scale projects and if there are any best known methods for
using them.

I do not have anything to share here since our projects did not have
such problems (not that large scale). It would be interesting to see
what you come up with. Maybe we can add some of that into core git to
support such large scale projects better. So maybe you can share exactly
what problems you have (only absolute paths?) or the pre-commit hooks
you will use.
