> And when compiling LO, you need a lot of temp space. So rather than having space dedicated to tmp for compiling, I have something like 10 or 20Gb of swap (plus 8Gb RAM), and simply have a huge tmpfs /tmp.
Why? Does it makes things faster for you? It would be interesting to see some benchmarks. I've seen tests showing there's no difference, and seen one with extfs being faster than tmpfs+swap for compiling.

Imho, it's much simpler to have it on disk. :)

/tmp is not the only place where you can mount tmpfs. If you want your /var/tmp/portage in tmpfs, you don't have to break other apps and put /tmp there.
