Colin Watson e760841d96 Add configure option to bypass boot menu if possible
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.

See the file INSTALL for instructions on how to build and install the
GRUB 2 data and program files.

See the file MAINTAINERS for information about the GRUB maintainers, etc.

If you found a security vulnerability in the GRUB please check the SECURITY
file to get more information how to properly report this kind of bugs to
