I realize this works for you, but in general Git's security model does
not permit untrusted configuration files or hooks.  Configuration can
have numerous different commands that Git may execute and it is not, in
general, safe to share across users.  This is why Git does not provide a
way to sync whole repositories, only the objects within them.

Adding the ability to transport configuration through a repository is a
security problem because it allows an attacker to potentially execute
arbitrary code on the user's machine, and I can tell you that many, many
people do clone untrusted repositories.  Just because you are aware of
the risks, are comfortable with them, and are the only user in this
scenario does not mean that this feature is a prudent one to add to Git.
It violates our own security model, and as such, isn't a feature we're
going to want to add.

I want to be clear that it is not that we don't see your use case as
valuable or important, only that we can't see a way to implement it
securely as proposed.  Warning users unfortunately isn't sufficient
because users tend not to read documentation.

Multiple core contributors representing various aspects of the Git
community have weighed in, and it looks like the answer is unanimous.

Sorry for the bad news.
