[Bug 671103] Re: backport grub-legacy-ec2 from maverick to lucid

[Scott Moser]

## I ran an instance of ami-8c0c5cc9
##  (us-west-1 ebs/ubuntu-lucid-10.04-i386-server-20101020)

% ec2-run-instances --region us-west-1 --instance-type t1.micro ami-
8c0c5cc9

## Then added -proposed archive and installed grub-legacy-ec2 and cloud-init
## and grub-pc (bug 671097)

$ apt-cache policy grub-legacy-ec2

## Now, after installing, on the client, I stop the instance and change
## the kernel to amazon's pv-grub kernel
## aki-99a0f1dc  ec2-public-images-us-west-1/pv-grub-hd0-V1.01-i386.gz.manifest.xml

% ec2-modify-instance-attribute --region us-west-1 --kernel aki-99a0f1dc ${iid}
% ec2-start-instances --region us-west-1 ${iid}

## Then, ssh to the started instance, and verify that options in
## /boot/grub/menu.lst actually took.  The command line should have 'console=hvc0' on it
## without using pv-grub, the kernel command line will only have 'root=/dev/sda1'.
