* 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. - Conflict with grub (<< 0.97-54) as well as grub-legacy. - 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. - If the environment variable "quiet" is set to something other than 0, suppress progress messages as the kernel and initrd load. Set this for non-recovery kernel menu entries. - Add GRUB_DEFAULT=saved, as well as grub-set-default and grub-reboot utilities. Provides functionality essentially equivalent to GRUB Legacy's savedefault. - 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. * Update savedefault patch from current Bazaar branch, fixing grub-reboot to have distinct behaviour from grub-set-default (LP: #497326). * Fix grub-mkisofs compilation error with FORTIFY_SOURCE. * Convert recordfail boilerplate in each menu entry to use a function.
