No you don't; you do it as part of the appropriate normal operations. * supermodule commit - scan the current tree for "link" objects in the tree. If you find one write the reference in the submodule. * adding a new submodule - if this is a new submodule there can't be any references in the supermodule already. * cloning a supermodule, every new commit that gets written in the supermodule gets checked from "link" objects. > So what do you do with deleted submodules? > You wouldn't want them to still sit around in your working directory, > but you still have to preserve them. Now that is a tricky one. Mind you, I think that problem exists for any implementation. I haven't got a good answer for that.
