Its actually not even passed to kexec, we build the initrd using the output of
uname -a, or override it manually with an option in /etc/sysconfig/kdump.  We
don't ever mount the /boot partition, so /boot/grub/menu.lst shouldn't be
accessible for re-writing.

Agreed, initramfs construction is a distro specific operation, the upstream
project doesn't contain bits on how to do that.
