I am yet to hear whether the warning is safe to ignore. Which one of the following is true? (1) Only 3955MiB of swap space will be used (instead of 4092MiB), but that reduced space will have maximum operational performance. (2) 4096MiB of swap space will be used, at reduced performance. To increase performance, the partitions have to be resized to (3955/4)MiB each.
