It won't be possible in general to emit what the function returned before, as `uname` is a symbolic reference to an arbitrary executable, which can vary by platform and release and local environment.

What I might be able to do is find the implementation of "uname" and see if there's a way to get the value from the same source. I did find what I believe is the [canonical source](https://github.com/coreutils/coreutils/blob/66e2daa689fefec9ed201a04696b9f52d049d89a/src/uname.c#L301-L343).

I'll explore if those calls can be translated to Python.
