As someone who's not an expert in linux or computers (I'm just a user, I don't really understand the internals of linux), does this mean or not that more RAM will be used?
This means that is should work a lot faster for typical workloads and that data in `/tmp` will automatically be cleared on reboot.
In theory it shouldn't affect anyone much, unless you have swapping disabled (which by default you won't).
I'm sure it's optional, or at least hope it is, cause it might not be good in all contexts
(On Arch, I had to undo what Debian is now doing on a laptop I have since updating some AUR packages would fail from lack of RAM. Now, they succeed and only take an hour!)
