Actually, I don't know if that even makes sense, because I don't know
what "labeling a partition" might amount to. Checking my sources again,
I see I need to add FILESYSTEM labels (I know what those are) to any
additional partitions, in the current, offset=0, setup.

Is it just irrelevant whether one adds them in the offset=1 setup?

What about labeling the filesystem in the first/fake/dd'd partition? are we suppose
to just leave that alone? Can we rely on the mkarchiso and archiso2dual
scripts to set that up properly, whether we do or don't go on to create
extra partitions on the device after dd'ing the ISO to it?
