`shell-file-name' is often wrong for remote systems; there could be
another OS, for example. "/bin/sh" is POSIX and can be assumed to exist.

How shall one know the remote login shell in advance?

And, in order to find a proper solution, maybe you could show a use case
where "/bin/sh" is simply wrong?

Best regards, Michael.
