So practically speaking: You mean that the value of
submodule.<name>.ignore is set to "all" in the master branch of the
superproject? From your other email referring to svn:externals I figure

I do not understand how does that ensure you get the correct submodule
revision when checking out a tagged release? To get a precise revision
the superproject needs to track a sha1 of a submodule commit. I do not
see how that has anything to do with submodule.<name>.branch?

This does not answer my question. I would like to find out the reason
why one would do the switch.

Here is the same. I am searching for a description like:
If the developer works on a feature that needs a submodule change he:
- creates a submodule branch
- configures that submodule branch in the superproject:
git config -f .gitmodules submodule.common.branch dev/some-feature
git commit -am "TEMP: track submodule common on branch"
- and pushes out his superproject branch
The submodule branch is then posted for review and continued to work on.
Once everyone involved is happy with the submodule change the branch in
there gets merged to master.
Now the branch in the superproject is modified to drop the change in
.gitmodules and the sha1 reference in the superproject is updated to the
current master of the superproject.
The superproject branch is posted for review.
Could you describe something like this for your workflow? A complete
change lifecycle when a developer works, as you call it, "actively" in a

To clarify you are talking about issuing "git merge" or "git rebase"
commands in the superproject?
