    Description

      If you add the path to a symbolic link to a file system watcher you'll not be notified if the symbolic link changes (also not if the symbolic link is removed).
      I checked on Linux (inotify) and Mac (kqueue).
      With inotify it doesn't seem to be a limitation of inotify itself (there's IN_DONT_FOLLOW, see http://inotify.aiken.cz/?section=inotify&page=faq&lang=en)

      Unfortunately that makes it hard to impossible for e.g. Qt Creator to handle external changes to symbolic links.
