This change updates grub to the 2.04 release. The new release changed how grub is built, so the bootstrap and bootstrap.conf files have to be added to the dist-git. Also, the gitignore file changed so it has to be updated. Since the patches have been forward ported to 2.04, there's no need for a logic to maintain a patch with the delta between the release and the grub master branch. So the release-to-master.patch is dropped and no longer is updated by the do-rebase script. Also since gnulib isn't part of the grub repository anymore and cloned by the boostrap tool, a gnulib tarball is included as other source file and copied before calling the bootstrap tool. That way grub can be built even in builders that only have access to the sources lookaside cache. Resolves: rhbz#1727279 Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>

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
|
|
