There was some discussion on fedora-devel-list about how to make it more obvious that the Fedora desktop spin. Various proposals were worked out to the point of working implementations.

Kamil Paral made the start with an extension that puts an ‘Install’ button in the top bar. I’ve followed up with a notification that pops up at login, explains that you are using live media, and offers you to install (The backstory here is that we’ve actually had a shell extension for showing the installer on the desktop spin for a while before F16, but the gnome-shell team asked that we ship GNOME 3 without extensions installed, so we’ve taken it out.). The notification was never my favourite approach to this issue; I preferred to just auto-start the installer.

We are very lucky that Cosimo Cecchi and Kalev Lember teamed up for an outstanding job, and got a much nicer solution implemented, polished and integrated in a matter of days, so the initial experience when booting the F17 desktop spin will be this:

I’m looking forward to it !
