Hey,

IIUYC I am not sure that this would solve Node's installation problem.

Because Node is an image (ISO) which is copied onto a Logical Volume
(LV). A seperate boot partition then points to the LV at boot time.

And this part - writing an image to a LV during installation - is what
might not be possible right now.

But maybe it can be added.
