cloud-initramfs-growroot is an initramfs module in cloud-initramfs-tools that resizes the root partition before the root is pivoted over. growroot was used in Ubuntu up to and including 12.10. The file /etc/growroot-disabled on the root filesystem was the only way of disabling the growing of the root partition. In cloud-init 0.7.2 cloud-init began resizing the root partition as growpart gained the ability to utilize 'ptupdate' in kernels > 3.8. This was a big improvement as now the user could disable or enable the growing of the root partition via user-data. In order to let users disable growing of / very simplistically cloud-init will now respect the presense of /etc/growroot-disabled unless config specifically tells it to ignore that file.
