You could open a pivot_root subprocess using the subprocess module, or
you could run pivot_root() directly using ctypes. I doubt any
preexisting Python module wraps pivot_root(), but I'd love to be
surprised. You may find that your Python module path does amusing
things right after the pivot, so

I would not call this is_subdict. That name does not
clearly express that all keys need to have the same
value.
