I see.

However, I still don't know whether this shall be fixed in
dirtrack.el. Maybe it would be better if Tramp could support.

I do not use dirtrack.el myself, so I need some guidance from you to
reproduce. You wrote as recipe:

(shell-dirtrack-mode 0)
(set-variable 'dirtrack-list "[REGEX]")
(dirtrack-mode 1)

What do you use as "[REGEX]"? Shouldn't this be a list?

Remote shells as implemented by Tramp do not provide any directory
information in the prompt. By default, the prompt looks like this:

/sudo:root@hostname: #$ 

How do you customize that prompt?

Best regards, Michael.
