That sounds good to me. One comment is that as mentioned in my previous email
Petitboot doesn't support having multiple initrds. That's because it kexecs a
kernel and the kexec_file_load(2) syscall only allows to pass a single initrd
file descriptor.

So you should check if arch is ppc64le and /sys/firmware/opal exists in the
20-grub.install script and only add the config initrd if that's not the case.

At least until Petitboot gets support for multiple initrds. In the meantime
it will just use the /etc/vconsole.conf if exists in the initramfs, which is
the current situation.
