The
--recurse-submodules
option togit reset
only works if there are already submodules to recurse into. In the case where we're promoting from one branch which has a submodule to one which doesn't, this will not cause a git submodule directory to be created. Instead, we need to explicitly initialize potential new submodules.We also need to handle the case where the submodule did exist but it was bumped by the promotion and so we need to update it.
Calling
git submodule update --init
handles both cases.
