[Bug 1014695] [NEW] need some mechanism to support /boot/grub/menu.lst and pv-grub

[Scott Moser]

Public bug reported:

Currently (12.04 and quantal at the moment) cloud-init creates a binary package called grub-legacy-ec2.  The purpose of grub-legacy-ec2 is really to 
 * support use of pv-grub, a xen paravirtualied bootloader, which reads a grub 0.97 style /boot/grub/menu.lst file
 * install along side of grub-pc.  The Ubuntu cloud-images that run on xen are identical at the filesystem level to those that run on kvm.  Having 2 images, or having the user need to install a specific package based on hypervisor is not desirable.

the grub-legacy-ec2 package basically represents a copy of grub (0.97)'s
update-grub code and required dependencies.  As that is the code that
updates /boot/grub/menu.lst.   It also includes some small bit of code
to determine if a kernel is sufficient to run on EC2 (based on the fact
that in the past some kernels did not run there).

So, this bug is a request to remove that function from cloud-init and
either put it into the grub package instead.
