On: Improved default settings for Linux machines

It would be good if you were to explain your reasoning for your changes.

As alluded to before, defaults are default for a reason. Having someone explain why they change them is a good exercise for both reader and author.

for example fiddling with swappyness means that you'll end up with less RAM for important things, like file cache.

I've added some notes explaining my reasoning. I hope that helps. I'll dig in and explain some of the settings more thoroughly in the future.
