Not a dupe of bug 906722, but it seems very similar.

Occasionally on openstack clouds, we're seeing the root partition not being/grown on first-boot as it should be.

This was reported, and I have observed it on precise alpha-2 and will attach console logs. It happens sporadically.

The output of the relevant section of initramfs in the failed case looks like this:

| Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done.
| Begin: Running /scripts/local-premount ... done.

In the successful case, it looks like this:

| Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done.

The code that is running here is growroot/scripts/local-bottom/growroot [1]
