      Try btrfs, where with only 5 hours of research you can create a swap file without writing the entire file.

      # and tell btrfs to not move or segment it.
      
      touch /swapfile999
      chmod 600 /swapfile999
      truncate -s 0 /swapfile999
      chattr +C /swapfile999
      fallocate -l 999G /swapfile999
      mkswap /swapfile999
      swapon /swapfile999 -p 200
