The issue isn't being able to add and remove other partitions on a disk,
but rather to change the size of the underlying partition for a filesystem
that is currently mounted. I tried again with util-linux-2.9g, but the
kernel still thinks the partition is the old size. I will have to look
into this to see if it is possible to update the kernel partition info
for the mounted partition with an IOCTL.
