mmrnmhrm: Correctly pass kernelParams.

We only defined kernelParams within the body of "let" but didn't
actually use the attribute in 2df7ee103a01da34c9c82235bc286dde35e0f1ba.

mmrnmhrm: Switch to new disk layout.

We now have two disks only and the disk containing the bootloader from
the previous layout is now gone so we need to write it to the new disks.

Of course, we also need to switch two swap devices as well.
