Re: NFS how to set up properly for netboot ???

	   Hi Wolfgang,

  Thank you for your reply and I am still not clear, sorry.  When you
said "I think it would be much better if you would place all these files
in one root directory like" What do you really meant all these files
because I don't really know what files should be in /root and what
directory should I share exactly.  I assumed that we should share /etc,
/usr, /dev, /lib etc... but what files should I inlude in 
/boot/client/root.  Also, in /etc/bootptab there is only one root 
directory that we allow to mount in my case it is /boot/client1/root.
I might confuse you because I don't know how really.  Thanks and I really
appriciated.
