Hello,

A way to move forward with the installer could be to propose an ISO
image starting a desktop-environment by default. The attached patch
modifies the installation image so that it starts a GNOME session. The
installer is then automatically started, inside a gnome-terminal.

The resulting ISO image is bigger: 3.9G without compression and 1.7G
with compression.

Now, I'm not sure this is something we want to merge as-is. Maybe, it's
time to port the installer to a GTK3 application, or a Web
application. As we already have something working, porting (gnu
installer) to a new graphical backend, could be not so hard.

I don't think I'll have the bandwidth to do this anytime soon, but is
someone is interested, I'm willing to help/review :).

Thanks,

Mathieu
