Comment 4 for bug 870121

Strike Comment #2 as incorrect.

The root cause of this is the ubuntu-meta package provides the "ubuntu-desktop" package. In turn, "ubuntu-desktop" requires "update-notifier-common" which provides /etc/apt/apt.conf.d/10periodic.

The cloud images install the server bits using the "server^" task list. This explains _why_ the bare metal and cloud-images don't get the update setting. Further, it explains why this was not caught when we started using live-builder to generate the cloud-images.

In terms of history the change was introduced between Lucid and Natty. All Natty and Oneiric images are affected. So to confirm smoser's comment's, this has existed for some time.

In my opinion, the fix is to mark update-notifier-common for the "server" task.
