* Resynchronise with Debian. Remaining changes: - Adjust for default Ubuntu boot options ("quiet splash"). - Default to hiding the menu; holding down Shift at boot will show it. - Set a monochromatic theme for Ubuntu. - Apply Ubuntu GRUB Legacy changes to legacy update-grub script: title, recovery mode, quiet option, tweak how memtest86+ is displayed, and use UUIDs where appropriate. - Fix backslash-escaping in merge_debconf_into_conf. - Remove "GNU/Linux" from default distributor string. - Add crashkernel= options if kdump and makedumpfile are available. - 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. - Allow Shift to interrupt 'sleep --interruptible'. - Don't display introductory message about line editing unless we're actually offering a shell prompt. Don't clear the screen just before booting if we never drew the menu in the first place. - Remove some verbose messages printed before reading the configuration file. - Suppress progress messages as the kernel and initrd load for non-recovery kernel menu entries. - Keep the loopback file open so that subsequent changes to the "root" environment variable don't affect it. - Change prepare_grub_to_access_device to handle filesystems loop-mounted on file images. - Ignore devices loop-mounted from files in 10_linux. - Show the boot menu if the previous boot failed, that is if it failed to get to the end of one of the normal runlevels. - Handle RAID devices containing virtio components. - Don't generate /boot/grub/device.map during grub-install or grub-mkconfig by default. - Adjust upgrade version checks for Ubuntu. - Change priority to optional to match the priority of grub. - Don't display "GRUB loading" unless Shift is held down. - Adjust versions of grub-doc and grub-legacy-doc conflicts to tolerate our backport of the grub-doc split. - Fix LVM/RAID probing in the absence of /boot/grub/device.map. - Look for .mo files in /usr/share/locale-langpack as well, in preference. - Make sure GRUB_TIMEOUT isn't quoted unnecessarily. - Probe all devices in 'grub-probe --target=drive' if /boot/grub/device.map is missing. - Adjust hostdisk id for hard disks, allowing grub-setup to use its standard workaround for broken BIOSes. - grub-common Breaks: lupin-support (<< 0.30) due to a grub-mkimage syntax change. - Build-depend on qemu-kvm rather than qemu-system for grub-pc tests. - Use qemu rather than qemu-system-i386. - Extend the EFI version of grub-install to be able to install into an EFI System Partition mounted on /boot/efi in a location that complies with the EFI specification. - Upgrade the installed core image when upgrading grub-efi-ia32 or grub-efi-amd64, although only if /boot/efi/EFI/ubuntu already exists. - Make grub-efi-ia32 and grub-efi-amd64 depend on efibootmgr so that grub-install works properly. * Canonicalise device paths when building a device map on the fly. * Program vesafb on BIOS systems rather than efifb, and return to enabling gfxpayload=keep by default if the kernel has the necessary support built-in.
