tmpfs uses as much memory as necessary and nothing more. In theory, it
doesn't hurt to add all your memory to it as tmpfs will start to swap
when you run out of memory. However, it is usually a better idea to
unmount the tmpfs and use a regular file system whenever you need more
space.
As Volker noted, it is probably best to use 2GB tmpfs and when you
emerge libreoffice, (and maybe firefox and co.) to switch back to using
a regular fs. You could also expand tmpfs so that it can eat all memory
not used by your applications under normal circumstances.
Example: `free -m`
total used free
-/+ buffers/cache: 4717 3053
So in my case I'm probably fine with a 3GB tmpfs while still avoiding
excessive swapping.
