I'm confronted with some problems when trying to configure gitosis on my Archlinux
http://wiki.archlinux.org/index.php/Setting_Up_Git_ACL_Using_gitosis
I referred to this wiki article and successfully installed gitosis.
$ sudo pacman -U gitosis-git-20090525-1-i686.pkg.tar.gz
$ sudo -H -u gitosis gitosis-init < /tmp/id_rsa.pub
And modified /srv/gitosis/.ssh/authorized_keys to include my local user's id_rsa.pub.
But when I run git clone as the local user,
$ git clone gitosis@host:gitosis-admin.git
It says
Initialized empty Git repository in /home/wyx/gitosis-admin/.git/
gitosis@10.132.140.73's password: *****
fatal: 'gitosis-admin.git' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
So the git clone operation failed. I'm wondering why it tries to initialize an empty git repository in my local user's directory (/home/wyx)? And since I've already added local user's id_rsa.pub in .ssh/authorized_keys, why does it still ask for password?
An empty repository was created because that's just how git works: it has to init a repo before it can start pulling remote objects into it. Unfortunately this means you'll have to manually delete the empty repo before you try cloning again.
As for why the clone failed, it looks like you're using the wrong syntax for the remote repository path; git clone doesn't use scp syntax. In fact, if you don't specify a clone protocol, I believe it assumes the git protocol rather than ssh, which would probably be why it asked you for a password. Try this instead:
$ git clone ssh://gitosis@host/~/gitosis-admin.git
