Automatically Boot Different Kernel on Fail With the Grub Fallback Options

Did you know you can configure grub to automatically fallback to a different boot entry if one was not successful? A pretty neat idea, especially for servers where you can now avoid a lot of head aches. It doesn't matter at what point the system hangs, grub will boot the other kernel the next time, unless the system boot completes and you tell it not to with another grub-set-default. Nice!
