Alternatively, reinstall the whole system using Logical Volume
Management (LVM), and never fiddle around with partition resizing,
partition moving/copying, not even with partitions at all. Never again
have to reboot for resizing your file systems, swap spaces or whatever
block devices.
Just call lvextend/lvreduce and resize2fs (or equivalent for your FS)
after umounting the affected file systems and your done.
