- FLAVOR: Ubuntu Desktop

- HEADLINE: Set vm.swappiness on install based on machine ram.

- DESCRIPTION: The difference in responsiveness can be remarkable if it's lowered on systems with more ram. Most laptops and pc's these days have 4gb on average but the ones with hdds will be very slow on ubuntu because of default vm.swappiness vm.dirty_ratio vm.dirty_background_ratio etc that are set for older machines. Adding this feature will make ubuntu a better experience for most nontechnical people.
