Bug#127971: boot-floppies: Missing loopback device and localhost in /etc/hosts

[Philip Blundell <philb@gnu.org>]

The appropriate stuff should get written to /etc/hosts and
/etc/network/interfaces when you choose "Reboot the system" from the main
menu, if the network hasn't ever been configured at that point.  It seems
that this didn't happen on your machine, for whatever reason.

Did you actually use this option, or did you continue the installation in 
some other way (e.g. using the new "chroot without rebooting", or by hitting
Ctrl-Alt-Delete, or anything of that kind)?
