I am aware that the server and desktop editions only differ by the packages installed, and I can install server packages (LAMP etc.) into a desktop edition and get the same thing.
However, I want to be able to completely change my desktop installation into a server edition. e.g: when I type
uname -a or
lsb_release -a it is supposed to say Ubuntu server or something. I currently have an 11.10 desktop installation with LAMP stack installed and the info displayed by apache is "Apache blah blah, on (Ubuntu) server.
Where does apache get this information that I am using an Ubuntu desktop installation and not a server one? Is there a config file(s) to edit?
