Right now, run_shell() in mount.py accepts both "sudo" and "omit_sudo" as parameters. It's better to accept only one of these two parameters. A call to run_shell() where both are set to opposing values will be buggy. Therefore, methods calling run_shell() must add "sudo" to command arguments before call and set omit_sudo to False in call. As a result of this change, methods like stat() and run_python() in mount.py are now modified to add "sudo" to command arguments and set omit_sudo to False within their own definitions.
