Why?

Greg, sorry, you keep writing as if we all are idiots, but keep refusing

Sorry, I can't understand what you mean. What would be the purpose of
this configuration and what benefits it would bring?

Anyway, let's forget about SCSI. Do you believe that struct device
should be created for all IP addresses on which an NFS server listen and
for all exports it exports?

I explained why it isn't a too good option in another e-mail.
