Ah, sure, I forgot to tell the most important bit :-( The greater part of what these updating routines do is making sure that the list of filesystems is consistent, updating the corresponding list in the root node, and opening the ports to the roots of these filesystems. If I don't do the update, the mountee will not be included in the list of merged filesystems and the user will not see the mountee's filesystem at all. Regards, scolobb
