Yup.

It should be, but may need some extra build setup work. All the
official installer and live images are built on casulana, our big
amd64 build machine. We have some infra for doing builds in qemu VMs
if needed, but I suspect that's going to be very slow. Meh, we can
work our a solution for that at some point

OK. However, do we expect the image to be usable on any real machines
as-is?
