AFAIK its the same for btrfs as for the first case you mentioned. If you change rootfs-dependencies, you'll need to make sure you rebuild the "stage1"-initramfs.. so call grub2-install. And then you'll also have to rebuild the normal initramfs. Reason is simple. If your boot-fs is btrfs (normally the fs where /boot is located) and it can not be completely assembled from within the "stage1"-grub environment (which is located at /boot/zipl), you'll not be able to load the normal kernel and initramfs. And AFAIK, that is the default SLES12 setup - or maybe that changed with SP2, I have not installed a fresh SP2, just upgraded.
