Comment 2 for bug 1398405

I disagree - MAAS should use gigabytes. I don't think many people know what
a GiB or Gibibyte is. Gigabyte is a well defined SI, IEEE etc term these
days and more commonly used. 'parted' uses gigabytes, drive vendors use
gigabytes. If MAAS uses gibibytes, the numbers it reports won't match what
end users expect. They know a system has a 128 GB drive - it's odd for it
to show up as 119 GiB instead.
