- You should not have a problem as long as you don't change the starting
- position of the g or h partitions. Change "a" to be the sum by using 137/0/0
- as the value for the size of the new "a" partition. Change "b" to 0. Label
- it and run newfs on the new "a" partition and you should be just fine.
