It will not die because it's cheap and simple to implement. People have designed better solutions for storage sharing that have been around for many, many years (DEC, SGI, IBM, Solaris, etc.). We're talking about smtp servers, here. SMTP is designed to deal with network outages. Email is inherently insecure as well. Your NFS server should be behind a firewall and only be accessible to your servers if you're concerned about security. With a virtual user qmail-ldap environment, the servers do not allow any user logins making the whole situation more secure. Solutions that are much more secure and stable than NFS have existed a long time, but they come at a much steeper price. Sure, NFS has gone far beyond what was intended, but it's still a viable solution. -- Clint Bullock Network Administrator University of Georgia Office of the Vice President for Research
