Comment 7 for bug 557913

I can see how this is confusing, but I don't think there's very much we can do about it, and it's not a recent change or anything. The manual partitioning summary displays what the state of the partition table is going to be after you commit changes. Partition numbers aren't stored anywhere in the partition table - they're calculated on the fly by the kernel etc. - so if you delete a partition then any partitions numerically after it *do* have their numbers changed, and the partitioner is just reflecting that fact.

Do you have any thoughts on how we could resolve the confusion here? I don't think it would be appropriate to leave the later partitions numbered in a way that doesn't match what their numbers will be after changes are committed, and right now I can't think of any other change that wouldn't do more harm than good ...
