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

[Scott Moser]

Long term, this would be a better path as the maintenance of menu.lst
does not really make sense in cloud-init, and debian has packaged cloud-
init without the grub-legacy-ec2 code.

Also, note in debian bug http://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=672104 the discussion there.

  need some mechanism to support /boot/grub/menu.lst and pv-grub

Bug description:
  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.
