That helps a lot Warren! In recent years I've just been creating a swap partition and one big root partition. It just seems as soon as I make all the traditional partitions, one runs out of room. Do you feel there are any major disadvantages of this approach? To create a swap and then a root that fills the rest of the disk, must the swap be created first, like this: gpart add -t freebsd-swap -a 4k -s 4g mirror/gm0s1 gpart add -t freebsd-ufs -a 4k mirror/gm0s1 Is there any other way to tell gpart to create the / partition using all space except 4G?
