submodules again

[Werner LEMBERG]

Folks,


the default operation (a) of `bootstrap' is clear:

  1. The `gnulib' submodule URL is in file `.gitmodules'.
  2. No special submodule entry in `.git/config'.
  3. A (submodule) clone of `gnulib' is created.
  4. All files of `gnulib' are checked out.

If I already have a local `gnulib' git repository elsewhere (b),
step 2 is different if I reference this local repository.

My question now is step 3 for situation (b).  IMHO it would be fully
sufficient to create the clone with the `--shared' option.  This saves
a lot of disk space, but `git submodule update' doesn't do this, and I
can't see an option to enforce it.

Is this my lack of understanding of submodules or is this is a missing
feature of `git submodule update'?

I'm using git 1.7.8.3 in case this is of importance.
