I have a public and a private git repository on the same machine, in
the same user's home directory. I want to ensure that when the public
repos is updated, the private repos automatically receives those
updates. Let's just assume that this is a good idea.

So, I've created a post-update hook script and made it executable. The
script is very simple. It 'cd's to the private repos and then does a
git pull. It looks, in essence, like this:

--
#!/bin/sh

cd /user/home/private/repos
git pull

exit 0
--

When I run this script directly, it works fine. (It also works fine
when I run it directly over ssh). However, when I do a git push to the
public repos, (either locally or remotely over ssh) the script is
called but reports back the following error:

--
fatal: Not a git repository: '.'
Failed to find a valid git directory.
--

Can anyone explain why this happens? And how can I make the script
work properly?

With sincere thanks for your help,

Geoffrey Ferrari

I'm no hook expert, but it may have something to do with some
environment variables that are set in hooks, you might need to change
variables like GIT_DIR.

Ack.

The hooks seem to assume repositories pushed into are bare, so the
GIT_DIR isn't set to a .git subdirectory (even if it exists).
