Since gene2fs can't produce large images in a reasonable amount of time, make a 64 meg image and resize it if necessary. (This means the minimum image size is 64 megs, because gene2fs won't run unless you specify a size, but it knows right away if the size you gave it wasn't big enough. I don't understand this either.)
