[arch-general] Install wiki - recommendations regarding 'swap' ?

All, After installing without AIF, I want to update the install wiki to drop a note about swap. It isn't addressed at all. What is the current Arch recommendation regarding swap creation? I.E.: recommended for systems w/less that 1G of RAM, create swap file of what size? (256M?) Even if swap is not recommended, I at least want to drop that note in the basic install. Thanks. -- David C. Rankin, J.D.,P.E.
