No, you are right, this option has nothing to do with file notifications: we always revert Dired buffers "by hand", whenever one of them is visited. So, back to the original issue: > But the sexp (dired test-dir) should (and in all my test runs does) > put point on the first "nontrivial" file (i.e. it skips "." and > ".."). In your case, does (dired test-dir) reads the directory anew, or does it revert an existing Dired buffer? I think the place to look for the problem depends on the answer to this question.
