There is always a common theme within teams at Dell to want to understand what consumers do with theirhardware after receiving it. Sometimes, a perception exists that the "Factory Installed Image" is inferior tothe content they could install themselves, or includes extra applications that would slow the machine down.
For the Linux factory shipped efforts, we strive to avoid adding anything that would get in the way of the consumergetting the absolute best performance and experience out of their machine.
To try to better understand what happens to machines that were shipped with Linux, a project has beencreated to anonymously chart the life of these machines after they leave the factory.
Of course in doing this, there are understandable privacy concerns, so the primary goal is to anonymouslygather information about how many machines are keeping their factory-shipped installations.
To achieve this, you may find that a custom source has been added in /etc/apt/sources.list.d that lookssomething like this:
deb http://9378ce1a78332da8d59223275f09727fe2ec1868.latitude.dell.archive.canonical.com/updates/ dell-lucid public
Whenever your APT client checks for updates (which you can control), this source will be contacted to showyou "checking in" and that your machine is still on the factory shipped image. There will be no packagesactually coming from this source, it's sole purpose is just record that a machine checked in.
As you can see, the source consists of a system specific unique hash and the line of business of your machine. This hash is a sha1sum of the service tag of the system. It can't be traced back to any particularperson, but allows the hash to persist even if you reinstall using the recovery image or upgrade to alater release.
If you are still uneasy with this extra source, feel free to remove it from your system, and your system will notbe counted.
