Why is zeitgeist datahub still installed?

[Scott(0)]

To reinforce what gold_finger's saying in the previous post I did a command line search on zeitgeist that resulted in what I beleive are the following 3 core packages (let me know if I'm wrong). I'm on LL 2.2/64 and not one of those packages is installed by default:

To list all the possible zeitgeist packages use this command

Code:

apt-cache search zeitgeist

Here's a partial list

Code:

zeitgeist
    event logging framework
zeitgeist-core
    event logging framework - engine
zeitgeist-datahub
    event logging framework - passive logging daemon

Notice the line - Installed: (none) - for each package

Code:

apt-cache policy zeitgeist
