How do I increase the EBS volume size of a running instance?

Question

I have a server running the recent Ubuntu AMIs from Canonical. The size of the EBS boot volume is 8GB. I know that I can resize EBS volumes by taking a snapshot, creating a new volume and expanding the partition on it. How can I increase the size of the volume while the machine is running?
