Format the second drive as one big vinum partition.  You can then manipulate
the space into different filesystems using vinum without affecting the other
partitions.  This is also nice as vinum allows you to turn non-contiguous
space into a single filesystem.  So, if you allocate 5G for a jail and then
realize you need 10G, you can allocate more space into the vinum partition
and use growfs to enlarge the filesystem.
