Make it 1G for /boot. I've actually used preupgrade in fedora, when I
brought a couple of workstations from FC17 to FC19, and it *needed* about
300G; I do *not* expect that to go down, and 1G, which we've decided on
and have been using at work for several years, should be ok.

Oh, and we've just defaulted to 2G swap (and my mind SEGV's when I mention
how much RAM some of our servers have....)
