I've been setting up all of my systems according to this, creating a 512MB swap partition: http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1&chap=4 If I have 4GB RAM, all I'm accomplishing with swap is increasing this to 4.5GB? If my system requires 4.6GB at some point, I'm in the same position I would be in if I had no swap and 4.1GB requirement? - Grant
