Thatʼs not what I observe:

~/.emacs:

        (message "Home dir")

/tmp/emacs-30/.emacs:

        (message "Temp dir")

src/emacs --init-directory=/tmp/emacs-30

=> *Messages* contains "Home dir"

So it looks like this option only affects `user-emacs-directory'.

I agree it would be less confusing if it used the ".emacs" in
"/tmp/emacs-30", but I think the ship has sailed on that one.
