I did the following on a 5.4-STABLE system and all the most recent
1) I created a symlink on my gnome desktop to /users.
2) Opened the directory in nautilus.
3) in a gnome-terminal, I typed "touch /users/ttt".
The nautilus view never updates. If I navigate through nautilus to the
actual directory (in Filesystem -> users), then it works as expected.
/users is a mount point
/dev/ad6s1d 180G 46G 120G 28% /users
