* 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 and an appropriate background for Ubuntu. - Apply Ubuntu GRUB Legacy changes to legacy update-grub script. - Fix backslash-escaping in merge_debconf_into_conf. - Remove "GNU/Linux" from default distributor string. - Add crashkernel option. - Bypass menu unless other OSes are installed or Shift is pressed. - Allow Shift to interrupt 'sleep --interruptible'. - Reduce visual clutter in normal mode. - Remove verbose messages printed before reading configuration. - Suppress kernel/initrd progress messages, except in recovery mode. - Show the boot menu if the previous boot failed. - Don't generate device.map during grub-install or grub-mkconfig. - Adjust upgrade version checks for Ubuntu. - Suppress "GRUB loading" message unless Shift is held down. - Adjust versions of grub-doc and grub-legacy-doc conflicts. - Fix LVM/RAID probing in the absence of /boot/grub/device.map. - Look for .mo files in /usr/share/locale-langpack first. - Build-depend on qemu-kvm rather than qemu-system for grub-pc tests. - Check hardware support before using gfxpayload=keep. - Put second and subsequent Linux menu entries in a submenu. - Preferred resolution detection for VBE. - Set vt.handoff=7 for smooth handoff to kernel graphical mode. - Update default/grub.md5sum to include maverick's default md5sum. - In recovery mode, add nomodeset to the Linux kernel arguments, and remove the 'set gfxpayload=keep' command. - Skip Windows os-prober entries on Wubi systems, and suppress the menu by default if those are the only other-OS entries. - Handle probing striped DM-RAID devices. - Replace 'single' by 'recovery' when friendly-recovery is installed. * Use qemu -no-kvm in tests for now to work around LP #947597. * Disable cursor as early as possible in grub_main (LP: #861048).
