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>

Subject: [PATCH] Accept ESC, F8 and holding SHIFT as user interrupt keys
|
|
|
|
On some devices the ESC key is the hotkey to enter the BIOS/EFI setup
|
|
screen, making it really hard to time pressing it right. Besides that
|
|
ESC is also pretty hard to discover for a user who does not know it
|
|
will unhide the menu.
|
|
|
|
This commit makes F8, which used to be the hotkey to show the Windows
|
|
boot menu during boot for a long long time, also interrupt sleeps /
|
|
stop the menu countdown.
|
|
|
|
This solves the ESC gets into the BIOS setup and also somewhat solves
|
|
the discoverability issue, but leaves the timing issue unresolved.
|
|
|
|
This commit fixes the timing issue by also adding support for keeping
|
|
SHIFT pressed during boot to stop the menu countdown. This matches
|
|
what Ubuntu is doing, which should also help with discoverability.
