[opensuse-virtual] after changes to 'xen.cfg' on a grub2 chainloaded Xen instance, what addl steps (mkconfig? mkinitrd? cp?) need to be exec'd?

I boot Xen on UEFI + grub2.

        uname -rm
                3.19.4-1.g74c332b-xen x86_64
        rpm -qa | grep -i xen-4
                xen-4.5.0_03-367.1.x86_64

Xen is chainloaded from grub2 config

        cat /boot/grub2/custom.cfg 
                menuentry 'xen' {
                        ...
                        chainloader /efi/xen/xen.efi
                }

        cat /boot/efi/efi/xen/xen.cfg
                [global]
                default=xen
                [xen]
                options=...
                kernel=vmlinuz-xen ...
                ramdisk=initrd-xen ...

each time a change is made to 'xen.cfg' which of these steps need to be 
executed to propagate fully to next boot?

        grub2-mkconfig -o /boot/grub2/grub.cfg
        mkinitrd
        /bin/cp -f /usr/lib64/efi/xen.efi /boot/vmlinuz-xen /boot/initrd-xen 
/boot/efi/efi/xen/

all of them?  in that order?
