But if you try to have one filesystem, with multiple people running git on their
machines against that shared filesystem, I would expect you to have all sorts of
problems.
What leads you to think you will have problems?
Why would there be more of a problem on a network file system as opposed to
local file system that can be accessed by multiple users?
There are safety checks and synchronization primitives that work between
mulitiple users on one machine (where you can see what other processes are
running for example) that don't work with separate machines using a filesystem
Linus seemed to think it should work:

well, he knows git better than I do, but using git over NFS/CIFS is not the same
as saying that you have multiple users on different systems making changes.
In the link you point at, he says that you can have problems with some types of
actions. He points out things like git prune, but I would also say that there
are probably race conditions if you have two git processes that try to change
the HEAD to different things at the same time.
And "git init" specifically has a "shared" option:
--shared[=(false|true|umask|group|all|world|everybody|0xxx)]
Specify that the git repository is to be shared amongst several users. This
allows users belonging to the same group to push into that repository. When
specified, the config variable "core.sharedRepository" is set so that files
and directories under $GIT_DIR are created with the requested permissions.
When not specified, git will use permissions reported by umask(2).
I think this is dealing with multiple users _reading_ a repository, not making
updates to it at the same time.
