The rationale here is that submodule.recursive ought to make your conglomerate of repositories (superproject + some submodules) look and feel like one giant repository. Thinking further this sounds like a user wants to set it globally, hence it may be expected to work for fresh clones, too. However at clone time, we don't know which submodules the user wants. The first submodule recursive switches were an all or nothing, but I think we need a better selection there. For fetch there is an "only-those-needed" selection as "on-demand". Similar for push. For clone we expected the user wanting to specify which submodules are interesting: git clone --recurse-submodule=<pathspec> (Note to self: the `[=<pathspec]` part is deep down in the man page, not in the synopsis, we may want to put that more prominently there) Maybe when submodule.recursive is set, we should assume a pathspec of "." (everything), also see to `submodule.active`, which is set using the argument from git-clone. >> "git help config" tells me that submodule.recurse affects >> all commands that have a --recurse-submodules option. >> git-clone seems to be an exception which is also mentioned in >> a workflow example in Documentation/gitsubmodules.txt that >> says: >> >> # Unlike the other commands below clone still needs >> # its own recurse flag: >> git clone --recurse <URL> <directory> >> cd <directory> >> >> So this seems to be a known issue.
