I fully agree with others' reluctance to use git submodules, and the
reasons they have expressed: git submodules are a major pain for
developers, and the concerns Liming listed above can be addressed in
other ways.
When my internal team first transitioned to git, we set up a complex
submodule-like system to (theoretically) allow easily updating common
code among different projects. That only lasted a month or two: having
to manage multiple repositories for day-to-day work, and the lack of a
single commit history spanning the entire tree doomed that scheme.
I collapsed everything together into a single repo using some git
filter-branch magic, and we've been happy ever since.
Please, no submodules....
Thanks,
