It won't do it automatically and I have never tried it but I am pretty
sure that once you have done the above swap you will then be able to go
in and create another partition on the free space. It is possible to
grow existing partitions into the free space too but this has to be done
with those partitions offline (unmounted) and is not for the feint of heart.
