It will use mostly unused ram for tmp files, but if it doesn't fit, the swap manager will swap it out to disk (think of a ramdisk with swapping). 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).
