I don't think this changes the default for anything in 6.x. He changed the default for his patch from yesterday that made it assume a type if you do 'mdconfig -s <size>'. Currently you have to do: 'mdconfig -a -t malloc -s <size>' or 'mdconfig -a -t swap -s <size>' but Nick changed it so just '-s <size>' implied '-a -t malloc', and now he's changed it to imply '-a -t swap'. -- John Baldwin
