Diskless Clients, Command Line Creation

[Jeff B]

I've been checking out system-config-netboot and I love how easy it
makes NFS Root deployment.  But the documentation does not tell how to
use the snap-shotting from the comand line.

I see that the manual tells how to use pxeos for doing network
installs. But nothing for new diskless hosts.

Is there a way, or what options are there for non-interactive diskless
host creation?
