I miss messages like

--8<---------------cut here---------------start------------->8---
file-notify-handle-event (file-notify ((2 . 0) stopped "/net/garfunkel/Multimedia/foo") auto-revert-notify-handler)
auto-revert-notify-handler ((2 . 0) stopped "/net/garfunkel/Multimedia/foo")
--8<---------------cut here---------------end--------------->8---

which I see in my test. "/net/garfunkel/Multimedia" is the mount point.

What is "/path/to/file.txt" exactly, and what is the related mount
point? You might send this information privately, if it is disclosed information.

Best regards, Michael.
