Maybe the error message should say so: "Bug your host admin to enable allowReachableSHA1InWant". > The interesting bit is that my submodule checkout still ends up being > shallow, but poiting to HEAD: > > ---8<--- > $ cd src/funTest/resources/projects/external/jgnash > $ git log > commit 12036fffb6c620515edd96416363fd1749b5d003 (grafted, HEAD -> master, > origin/master, origin/HEAD) > Author: Craig Cavanaugh <jgnash.de...@gmail.com> > Date: Tue Apr 18 05:33:06 2017 -0400 > > Fix typos > ---8<--- > > Wouldn't it make more sense to unshallow the submodule clone in this case and > checkout the configured commit 2aa4cce7d7fd46164030f2b4d244c4b89e77f722 > afterwards? If I remember correctly the conclusion of the discussion at the time was that people are more interested in "less data" rather than "correct data" because otherwise you would not have asked for shallow. > At least I'd be getting what I asked for in that case, even if at the cost of > additional network traffic.

Heh, good point. Currently that option is more like a "--[no-]follow-shallow-in-gitmodules" without second thought as the "recommend" would elude to.
