I got excited, since e.g. performance improvements would be of great benefit to us too. In our project, http://datalad.org, git submodules is the basic mechanism to bring multiple "datasets" (mix of git and git-annex'ed repositories) under the same roof so we could non-ambiguously version them all at any level. http://datasets.datalad.org ATM provides quite a sizeable (ATM 370 repositories, up to 4 levels deep) hierarchy of git/git-annex repositories all tied together via git submodules mechanism. And as the collection grows, interactions with it become slower, so additional options (such as --ignore-submodules=dirty to status) become our friends. So I thought to share this as a use-case happen you need more motivation or just a real-case test-bed for your work. And thank you again for making Git even Greater. P.S. Please CCme in your replies (if any), I am not on the list With best regards, -- Yaroslav O.
