in current world, cloud-initramfs-growroot grows the partition table from
the initramfs before / is in use, so the kernel can then re-read the
partition table.

then, cloud-init invokes resize2fs.


In future world (really close in ubuntu images for raring), cloud-init
invokes growpart (or parted) and then resize2fs.  3.8 kernel can be told
about the grown partition and growpart and parted (patches submitted) know
how to do that.
