But isn't that all handled automatically by grub2-install? It rebuilds
the stage1-initramfs and also executes zipl AFAIK, and you don't have to
care about the "bloody" details, like which initrd to copy and what
zipl-config to use.
Anyway I just wanted to share some awareness, because I "bricked"
already one (development) VM because I tried exactly this - extending
btrfs with a second DASD - and forgot to rebuild the stage1 zipl and
initramfs.
