org-latex-preview symlink handling

Long listener, first time caller

org-latex-preview was failing with: org-compile-file: File
"/private/var/folders/5b/m1bt7sss2n19dwg1d62h_hrw0000gn/T/orgtexGt3N0x.dvi"
wasn’t produced. Please adjust ‘dvipng’ part of
‘org-preview-latex-process-alist’.

Root cause was that on my system ~/org is a symlink to some icloud auto
sync directory (for beorg).

After much stumbling (despite my 10+ years of daily emacs use I haven't
much explored the lispy bowels!) I landed on the following solution:

    (setq org-preview-latex-process-alist
          '((dvipng :programs ("latex" "dvipng")
                    :description "dvi > png"
                    :message "You need to install the programs: latex and
dvipng."
                    :image-input-type "dvi"
                    :image-output-type "png"
                    :image-size-adjust (1.0 . 1.0)
                    :latex-compiler ("latex -interaction nonstopmode
-output-directory %o %f")
                    :image-converter ("dvipng -D %D -T tight -o %o/%b.png
%o/%b.dvi"))))

    (defun my/org-latex-preview ()
      (let ((find-file-visit-truename t)
            (vc-follow-symlinks t))
        (org-latex-preview)))

    (defun my/org-latex-preview-buffer ()
      (let ((find-file-visit-truename t)
            (vc-follow-symlinks t))
        (org-latex-preview-buffer)))

Could the default symlink behavior be improved?
