What possible value does this have? (Not even > Sun, the original purveyors of the 2x RAM rule, need this any more). RAM is still about 100x more expensive than HD. So I always recommend you use about 2% of the money you spent on RAM to pay for the HD space to handle swap. Actually the deal is: either use enough swap (about 2x RAM) or use none at all. A "good" operating system will want to use say half your memory for buffers, even if there are processes using that half of your RAM. Not when they are actively using it, but only after they have NOT used it for say an hour. Then the users of the machine will see efficient use of the resources. It does have the disadvantage that when you come back in the morning, your xterm may have been swapped out because of the nightly backups and stuff....
