+== NFS and inotify ==
+
+NFS does not work well with inotify. If a directory is exported through NFS and an NFS client writes to this directory through NFS, this creates thousands of CLOSE events instead of a single event.
+
+Therefore inotify cannot be used on a directory exported through NFS. PPSS tries to detect this by reading /etc/exports. If the source directory resides in a directory as found in /etc/exports, inotify is disabled.
