- By the time the GS is actually written, new (for partition state)
is always false. So "new" is the wrong thing to track. It should
have had a better name anyway,
- We store custom properties on the partition objects to indicate
what happens to them; use those properties (instead of state,
as done originally), call it "claimed" to indicate that the partition
is part of this installation.
For now, only new (as in, formatted, created-by-us) partitions are
claimed.
- The effect here is that only "new" swap will be added to the system,
so in erase-disk installations, or manual partitioning.
- Install-alongside and replace will now **not** claim the swap already
on the disk; I think we'll need another UI knob for that one.
