This behavior makes it possible to simply "switch on" or "switch off" the referral without having to move the directory's file data. Can you explain this a little more? > - autofs incompatibility, if you use a referral, and autofs encounters > it, you get a deadlock This one seems like a bug that should be fixed instead of documented.
