I suppose you could do that, assuming you also configured to have a  
local shell on the client.
You'd have to edit your NFS conf file to make the client chroot  
export read-write instead of read only and restart NFS. Then boot the  
client to a local shell and make your changes from there, and then  
change your settings back.  That's why I suggested chrooting into the  
client root on the server. I thought it would be less work.
