Title:
  support grub-emu and kexec loader

Status in grub2 package in Ubuntu:
  Expired

Bug description:
  In search of a netboot solution for system z, I found
   https://share.confex.com/share/123/webprogram/Session15694.html
  which discusses some work suse has done to support kexec from grub-emu.
  The end result is that they an boot kernel+initrd and execute grub-emu and have it load grub config files and load the operating system kernel.

  This is very similar in path to the way that powerNV works, where
  there is kernel+initrd and petitboot.

  Either solution to provide a netboot functionality will require addressing some interesting platform characteristics of zSeries.
  At very least there is no common way to determine inside a zVM guest which of the network devices is "yours" to use.  That is commonly passed in in kernel parameters.

  More information is available at
   https://share.confex.com/share/123/webprogram/Session15694.html
