That's correct.

I'd suspect that petitboot might do the boot device selection differently,
and might eventually end up choosing a boot device if one is not set in NVRAM,
or might use a different NVRAM key/variable for it.
It's possible, as the pseries (powervm) and powernv (opal) platforms are distinct, thus can do things differently.
