Comment 1 for bug 203977

This isn't an accurate representation of the question that was originally asked. The question was whether we could arrange for settings made while using the live CD to be copied over to the installed system.

We did consider this when we initially designed the live CD installer, but were very concerned that doing so would render installations much less supportable. In other words, you might (accidentally) completely screw up the live CD environment such that GNOME wouldn't be able to start, then install Ubuntu, and then complain when GNOME doesn't start. Also, it is rather difficult to distinguish customisations made automatically during the live CD boot process from deliberate user customisations. Thus, I don't expect that this is a feature we will be able to offer soon. I would rather make it clear to users that changes they make while running the live CD will not be preserved.

(Selecting a list of applications to install is much less feasible, because the live CD installer works by simply copying over a filesystem and isn't really set up for package selection. You're much better off simply installing them afterwards anyway; if you want to deploy many systems that way then the alternate installer or netboot is available.)
