Re: boot cd-rom network install on system with no display using vnc

The reason for:

   prompt 0
   timeout 0
is there is no keyboard or screen, so whats the point of having a prompt or 
delay.

If the CD is accidentally used in a machine, it will boot into the red Hat 
installer, but since there is no kickstart file specified, the automatic install 
wouldn't happen.

A label written on top of the CD explaining its purpose will stop accidental 
usage.

/root/isolinux/isolinux.cfg file like this:

   default linux
   prompt 0
   timeout 0

The parts above allow the system to start automatically
with no operator intervention

Downside is, if anyone inadvertently puts this CD in a system
and reboots, or the system itself reboots, 
it will install!

You have to make your own boot cd and insert the information I provided into the 
isolinux.cfg.
