Bug Description
In search of a netboot solution for system z, I found
https:/
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.
