I fear this is not sufficient. This patch handles only file
notifications which are implemented via tramp-sh.el.

Yesterday, I have committed a patch which adds
`tramp-gvfs-handle-file-notify-add-watch' (using gvfs-monitor-file to
poll for changes on GVFS mounted directories).

Maybe we rethink to introduce `file-notify-supported-p' and its
handlers?

Best regards, Michael.

PS: Don't worry when I do not react next days. Tomorrow I'll start a
bike tour, and unfortunately my companions insist on the basic rule "no
electronic devices on board".

You'd know better than me, I was just tying to get rid of the

(ert-test-failed
   (file-notify-error "No file notification program found on /ssh:localhost:"))

from eg
http://hydra.nixos.org/build/5635144/log/raw

It succeeds in that regard.

Does it matter outside of automated testing if one gets an error?

Good for them! :)

I'll think about.

`file-notify-add-watch' promises to raise an error in such a
situation. It would matter, when it silently returns.

Best regards, Michael.
