Explain why iterative navigation is necessary in a name service in which different name spaces are partially integrated, such as the file naming scheme provided by NFS.
What will be an ideal response?
The reason why iterative navigation is necessary is that when a client encounters a symbolic link, then this symbolic link should be resolved with respect to the client’s name space, even when the server stores the link. For example, suppose that the server’s directory /jewel is mounted on the client’s directory /ruby/red. Suppose that /ruby/red/stone (stored in the server’s name space as /jewel/stone) is a symbolic link to /ruby/stone. The server passes back this link to the client, which then must continue to resolve it. The pathname /ruby/stone might refer to a file stored at the client, or it might be a mount point to another server.
