With my emacs started from PATH with "emacs" where emacs is a symlink:

    /usr/local/sbin/emacs-28.0.50/emacs-28.0.50

which is the correct path:

    (expand-file-name invocation-name invocation-directory)

==>/usr/local/bin/emacs

    (file-truename "/usr/local/bin/emacs")

==> /usr/local/sbin/emacs-28.0.50/emacs-28.0.50
