The vendor class identifier with the string "HTTPClient" is used to denote the
packet as responding to HTTP boot request. In DHCP4 config, the filename for
HTTP boot is the URL of the boot file while for PXE boot it is the path to the
boot file. As a consequence, the next-server becomes obseleted because the HTTP
URL already contains the server address for the boot file. For DHCP6 config,
there's no difference definition in existing config as dhcp6.bootfile-url can
be used to specify URL for both HTTP and PXE boot file.
This patch adds processing for "HTTPClient" vendor class identifier in DHCPACK
packet by treating it as HTTP format, not as the PXE format.

zfs-initramfs currently provides extraneous, undesired symlinks to
devices directly underneath /dev/ to satisfy zpool's historical output
of unqualified device names. By including this environment variable to
signal our intent to zpool, zfs-linux packages can drop the symlink
behavior when updating to its upstream or backported output behavior.

Add an extra option to grub-install "--force-extra-removable". On EFI
platforms, this will cause an extra copy of the grub-efi image to be
written to the appropriate removable media patch
/boot/efi/EFI/BOOT/BOOT$ARCH.EFI as well. This will help with broken
UEFI implementations where the firmware does not work when configured
with new boot paths.

Some powerpc machines require not updating the NVRAM. This can be handled
by existing grub-install command-line options, but it's friendlier to detect
this automatically.
On chrp_ibm machines, use the nvram utility rather than nvsetenv. (This
is possibly suitable for other machines too, but that needs to be
verified.)

Since we're already being booted from the Windows boot loader, including

If other operating systems are installed, then automatically unhide the
menu. Otherwise, if GRUB_HIDDEN_TIMEOUT is 0, then use keystatus if
available to check whether Shift is pressed. If it is, show the menu,
otherwise boot immediately. If keystatus is not available, then fall
back to a short delay interruptible with Escape.
This may or may not remain Ubuntu-specific, although it's not obviously
wanted upstream. It implements a requirement of
https://wiki.ubuntu.com/DesktopExperienceTeam/KarmicBootExperienceDesignSpec#Bootloader.
If the previous boot failed (defined as failing to get to the end of one
of the normal runlevels), then show the boot menu regardless.

If this option is enabled, then do all of the following:
Don't display introductory message about line editing unless we're
actually offering a shell prompt. (This is believed to be a workaround
for a different bug. We'll go with this for now, but will drop this in
favour of a better fix upstream if somebody figures out what that is.)
Don't clear the screen just before booting if we never drew the menu in
the first place.
Remove verbose messages printed before reading configuration. In some
ways this is awkward because it makes debugging harder, but it's a
requirement for a smooth-looking boot process; we may be able to do
better in future. Upstream doesn't want this, though.
Disable the cursor as well, for similar reasons of tidiness.
Suppress kernel/initrd progress messages, except in recovery mode.
Suppress "GRUB loading" message unless Shift is held down. Upstream
doesn't want this, as it makes debugging harder. Ubuntu wants it to
provide a cleaner boot experience.

Patch-Name: install-efi-fallback.patch
Since files in /etc/grub.d/ are conffiles, they are not put in place
until grub-common is configured, meaning that they may be out of sync
with the parts of grub-mkconfig that reside in /usr/. In GRUB 1.99,
/etc/grub.d/00_header contained a reference to ${GRUB_PREFIX}/video.lst.
This and other code from 1.99 breaks with 2.00's grub-mkconfig.
Deferring this to when grub-PLATFORM.postinst eventually runs is safe
and avoids this problem.

Improve prepare_grub_to_access_device to emit appropriate commands for
such filesystems, and ignore them in Linux grub.d scripts.
This is needed for Ubuntu's Wubi installation method.
This patch isn't inherently Debian/Ubuntu-specific. losetup and
/proc/mounts are Linux-specific, though, so we might need to refine this
before sending it upstream. The changes to the Linux grub.d scripts
might be better handled by integrating 10_lupin properly instead.
Patch-Name: mkconfig-loopback.patch
Setting gfxpayload=keep has been known to cause efifb to be
inappropriately enabled. In any case, with the current Linux kernel the
result of this option is that early kernelspace will be unable to print
anything to the console, so (for example) if boot fails and you end up
dumped to an initramfs prompt, you won't be able to see anything on the
screen. As such it shouldn't be enabled by default in Debian, no matter
what kernel options are enabled.
gfxpayload=keep is a good idea but rather ahead of its time ...

On UEFI, 'text' gfxpayload is not supported, but we still reach parse_modespec()
with it, which will obviously fail. Fortunately, whatever gfxpayload is set,
we still still have the 'auto' default to fall back to. Allow getting to this
fallback by not trying to parse 'text' as a modespec.
This is because 'text' correctly doesn't parse as a modespec, and ought to have
been ignored before we got to that point, just like it is immediately picked if
we're running on a system where 'text' is a supported video mode.
