Randall, Perhaps I was using imprecise terminology. This change should not impact whether submodule clones land in a detached head state, so it should not impact anything that assumes submodule clones are detached head. The change being made is this: "git clone --recurse-submodules --shallow-submodules" currently gives you a submodule with a detached head at the desired state, but also downloads data for the tips of all branches in the remote being cloned (potentially a lot of unneeded data as in my use case). The modification means the same command would give you a detached head at the desired state, plus the tip of only the default branch in the remote. The modified behavior matches the current behavior for a simple "git clone" followed by "git submodule update --init --recurse--submodules --depth=1".

Many CI systems (including Jenkins GitSCM) assume a detached head for submodule clone/checkout. Adding a branch to the mix will change the expected semantics. Am I missing something? > --Randall >
