If the system is set to have root on NFS. And the root is not found
what does it do? does it Just bums out with a recovery console?

So what better options does it have other then retry for ever. die?

I always thought that was inconsistent. With an hard mount NFS
will never give up and will retry for ever freezing all IOers until
the server came back. Only with root-mount it gives up.

Please explain what is the benefits of giving up at all. Can a machine
be at all usable without it's root? 

Thanks
