Hi @laoyang360,

we use `git -C` internally in Rally to simplify git operations in different directories. From the git man page:

> -C \< path \>  
> Run as if git was started in instead of the current working directory.

As far as I know this option has been added in git 1.8.5 but they had some bugs. Great that you've resolved the problem now though.
