Could you post a backtrace for the "doesn't like it" case?
Sure. It is Emacs-26 that errors.
As far as I can see, this will only affect the edge case of someone
running two versions of Emacs. I tend to do this (I run gnus in a
standalone release emacs, and everything else in another emacs).
Commit b663c837249 (in May) which says "Cosmetic changes" is the one
that introduced this code?
(let ((olddir (or (getenv "TMPDIR") "/tmp")))
(when (and (equal dir (format "%s/emacs" (getenv
"XDG_RUNTIME_DIR")))
(file-writable-p olddir))
(let ((link (format "%s/emacs%d" olddir (user-uid))))
(unless (file-directory-p link)
;; We're using the new location, so try and setup a symlink
from

emacsclient.
;; FIXME: Check that it's safe to use!
(make-symbolic-link dir link t)))))
And instead of making things work with an old emacsclient, it breaks
the
Emacs 26 emacsclient?
