 ==== Cleanup ====
 There are a few things that can be removed at this point to clean up your install to reduce resource use and protect your privacy.
-When you type a command that's not found on your $PATH, Ubuntu will try to look it up and recommend packages to install that may be what you're looking for. This often means that instead of a quick error message, there is a delay before returning to a prompt. You can stop this behavior by removing the command-not-found package.

-You may have noticed that on login, your MOTD contains a lot of information, some of which is dynamically generated from sources on the internet. One of these steps sends information about the machine to Ubuntu as part of the request for latest news. We can disable this in /etc/default/motd-news.

-You can take this further and move or delete the files found in /etc/update-motd.d/ and optionally replace them with your own script. On login, Ubuntu will execute the scripts in this folder and display anything they send to stdout. You can also create /etc/motd and any text in that file will be displayed after any output from your motd scripts.
