Hello,

Since the instructions say that bugs should be reported on the mailing
list, I do so here.

When visiting a file by tramp over ssh, doing latex preview fails.

* Version

Tag 9.4.6 (commit:652430128)

* To reproduce:

Create the following org file:

#+begin_example
* Testing formulas
\[\xi^2+\chi^2\]
#+end_example

and invoke =org-latex-preview=.

The result is that org-latex preview fails finding the temporary tex file
(which was saved on the remote server)

#+begin_example
This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017) (preloaded
format=latex)
 restricted \write18 enabled.
entering extended mode
! I can't find file `/tmp/orgtexq5rOVI.tex'.
<*> /tmp/orgtexq5rOVI.tex

(Press Enter to retry, or Control-D to exit)
Please type another input file name
! Emergency stop.
<*> /tmp/orgtexq5rOVI.tex

No pages of output.
Transcript written on /tmp//texput.log.
#+end_example


Regards,
Dov

Confirmed.

I just tried this by creating an Org file on a Debian server (I run OpenSUSE
with TexLive 2021). From looking at the `*Org Preview LaTeX Output*' buffer, it
appears that the temp file is created on my local machine, and then the process
is called on the remote machine.

┌────

│  restricted \write18 enabled.

└────

Having a look at `org-create-formula-image', I suspect this is due to the
`make-temp-name' call at
<https://git.savannah.gnu.org/cgit/emacs/org-mode.git/tree/lisp/org.el#n16521>.
Perhaps `tramp-make-tramp-temp-name' could be useful?

All the best,
Timothy
