It is not a bug. If you want to use the same swap partition with multiple install, then you should not reformat the swap partition. How can the installer guess that you want to use the same swap partition for multiple OS. (reinstalling the same system is a common task -- but i always wonder why ...) Maybe you want to add warning message before formatting like "Care, a swap partition already exist at /dev/sdaXX, would you like to reformat it ?" IMO, you should know what you're doing. It's not the installer job to "think" for you ! The installer just does what you ask him to do ! > My expected behavior would be to check to see if a swap area already > exists before "creating" a swap partition.
