Thanks for the clarification. I didn't use LVM on the device on purpose,
as root on LVM requires initrd (which I strongly dislike as
yet-another-point-of-failure). As LVM is on the large partition anyway
I'll just add the second partition for now, and change the system setup
with the next drive migration. Maybe linux even supports root-on-lvm
natively until then ;)
