Is this really a good idea? Will vos move give a warning when moving a 
volume from one flavor of server to another? What happens when a server 
is rebooted with the flag switched? Would we need some kind of flag on 
the volume itself to say what kind of behavior is expected? This may be 
a 5 minute change, but recovery may take years. Maybe with a little more 
thought we can come up with a way to get the specific desired behavior 
without making multiple flavors of file servers (and avoid the resulting 
confusion that will ensue).
