Hi James,
The MAC address is set correctly, it is properly using the pxelinux.cfg
file associated with the MAC address.
When I view the kickstart file that the system is booting using a web
browser, I see the line "%include /tmp/pre_install_network_config". Is
that correct?
Yes. Are you using the sample.ks file we ship or one you've created
yourself? There should be a snippet in the %pre section which generates
that file. When you get the error you're seeing, it means that file isn't
being created. The typical cause of that file not being created is what I
said before.
Use the command "cobbler system getks --name=sysname" to view the ks as it
will be downloaded by the system and look for errors, especially in the
%pre section.
The error when booting is "Unable to open input kickstart file: Could not
open/read file:///tmp/pre_install_network_config"
In the redhat bugzilla a user comments that:
"%pre does not get executed in initrd. It gets executed by anaconda
proper.
This worked in F16 by coincidence, because the entire anaconda
runtime was
inside the initrd. It would not have worked in any release prior to F15
and F16."
