Users experienced with Gentoo’s console install method may be familiar with net-setup, a simple ncurses/dialog utility to configure network interfaces. It can also be used on a live system (found in the app-misc/livecd-tools package).
One source of confusion during installation is the naming of network interfaces – this is sometimes different from the naming on a live system (eth0 swaps with eth1, etc).
I added two additional dialogs to the net-setup wizard which attempt to make it clear to the user exactly which interface is which. The data mostly comes from sysfs. Here are some screenshots:
This will be available in the next livecd-tools release.
