Hmm. In the Elisp manual, you have added to `set-file-modes':

--8<---------------cut here---------------start------------->8---
On platforms that do not support changing mode bits on a symbolic link,
this function signals an error when FILENAME is a symbolic link and FLAG
is ‘nofollow’.
--8<---------------cut here---------------end--------------->8---

Shouldn't Tramp behave similar, and raise an error if "chmod -h" or
something similar does not work? "Equal rights for all" :-)

Best regards, Michael.
