Yes, concurrent attempts to update a branch are serialized. (But please don't ask me to answer about NFS semantics. See

http://stackoverflow.com/questions/750765/concurrency-in-a-git-repo-on-a-network-shared-folder

for some notes.) See the note about fast-fowards in the git push manual for how integrity is preserved.

After reading that, you might wonder: if there are many, many clients pushing to the same branch, how is starvation avoided? Good question! It isn't. If you have so many clients wanting to push to a single branch, I would suggest having a single person or a few people maintaining it, pulling from others. Life will be better for many reasons, especially quality control.

Hope that helps. Jonathan
