    path = os.path.expanduser(path)

    if not os.path.isabs(path):
        raise SaltInvocationError('File path must be absolute.')

    if not os.path.isdir(path):
        raise SaltInvocationError('A valid directory was not specified.')

    try:
        os.rmdir(path)
        return True
    except OSError as exc:
        return exc.strerror
