What is the difference in the export options /pathname -ro -root and /pathname -ro -anon?
When you specify /pathname -ro -root, the path is exported as read-only with root access to all clients. However, when you specify /pathname -ro -anon, the path is exported as read-only with anonymous access to all clients. If you do not specify the anon option, then on the client side root cannot do any operations on the mount point.Even executing a cd to the mount point is not allowed.
