#git_bin_dir ⇒ Object

Unix users do not want git on their path if they already have it installed. Because we put ‘embedded/bin` on the path we must move the git binaries somewhere else that we can append to the end of the path. This is only a temporary solution - see github.com/chef/chef-dk/issues/854 for a better proposed solution.
