Linus says that git does not have "proper locking", so think about it,

you think will happen if person A does git add a/b; git commit and person
B does
git add c/d; git commit?
Sorry, I wasn't clear. My assumption is that a shared repository on a network file system will either be:
1. a bare repository that is normally accessed only by "git push" and "git pull" (or "git fetch"), the central repository model.
pulling from it would not be a problem, I could see issues with multiple pushes
taking place (the underlying repository would not get corrupted, but you will
very quickly hit conflicts where the push is not a fast forward and you need to
merge, not just push)
2. a repository where only one user does "git add" and "git commit", while
other users will do "git pull", the peer-to-peer model (you pull changes from
me, I pull changes from you).
At this point only one system is writing to the repository and it doesn't matter
that it's on network storage vs local storage.
pulling from a shared repository is probably safe, but I wouldn't bet against
there being any conditions where a pull at the same time someone is doing an
update being able to cause problems.
The normal thing is to do the pulls through git-daemon, and that does make sure
that what you are pulling is consistant.
