Before I used OpenEmbedded, I had a custom build system with submodules. 
It was a usability nightmare - there were a lot of cases where the 
submodule tree was pushed but the parent wasn't committed and pushed, or 
vice versa, or somebody reverted to a previous rev of a submodule because 
they didn't "git submodule update" and ran "git commit -a" without 
checking.

For our srctree/gitver projects we almost always want to track the latest 
version, so a shell script that runs "git pull" in every directory works 
much better for us than submodules did.
