Then follow instructions printed out by grub-mknetdir on configuring your DHCP
|
|
server.
|
|
|
|
+The grub.cfg file is placed in the same directory as the path output by
|
|
+grub-mknetdir hereafter referred to as FWPATH. GRUB will search for its
|
|
+configuration files in order using the following rules where the appended
|
|
+value corresponds to a value on the client machine.
|
|
+
|
|
+@example
|
|
+@group
|
|
+@samp{(FWPATH)}/grub.cfg-@samp{(UUID OF NIC)}
|
|
+@samp{(FWPATH)}/grub.cfg-@samp{(MAC ADDRESS OF NIC)}
|
|
+@samp{(FWPATH)}/grub.cfg-@samp{(IPv4 OR IPv6 ADDRESS)}
|
|
+@samp{(FWPATH)}/grub.cfg
|
|
+@end group
|
|
+@end example
|
|
+
|
|
+The client will only attempt to look up an IPv6 address config once, however,
|
|
+it will try the IPv4 multiple times. The concrete example below shows what
|
|
+would happen under the IPv4 case.
|
|
+
|
|
+@example
|
|
+@group
|
|
+UUID: 7726a678-7fc0-4853-a4f6-c85ac36a120a
|
|
+MAC: 52:54:00:ec:33:81
|
|
+IPV4: 10.0.0.130 (0A000082)
|
|
+@end group
|
|
+@end example
|
|
+
|
|
+@example
|
|
+@group
|
|
+@samp{(FWPATH)}/grub.cfg-7726a678-7fc0-4853-a4f6-c85ac36a120a

After GRUB has started, files on the TFTP server will be accessible via the

@samp{(tftp)} device.
