Resize root volume in ramdisk

I have heard that, for older versions of Linux kernel, it is not possible to resize the root partition after the kernel mounts the disk. So, if your image is smaller than the root volume of the flavor (e.g., your image is 10GB but your m1.custom flavor has a 20GB root volume), you need to configure the ramdisk to do the resize early enough in the boot cycle.

How do you do this?

Robert Plestenjak has a project on github called centos-image-resize that contains a script for modifying an initrd image and grub menu to do the rseize. It uses the growpart tool from cloud-utils
