Package: debian-installer Version: 20070308 Priority: wishlist I've recently tried to setup a Debian 'etch' install using d-i with no network connection. One of the bugs I've found is that, even if the network card is down, DNS resolution does not work and the default gateway is not available, d-i goes and tries to download stuff when I select a mirror that I will use (but it is not yet available). However, since d-i is not able to validate the mirror, the mirror I selected (based on my location) cannot be set and added to /etc/apt/sources.list. I think that d-i should (if network is unavailable), just add the mirror to /etc/apt/sources.list and skip all the validation steps if the user ackonwledges the fact. Attached is a crude hack to choose-mirror.c that tries to explain (in code) what I'm asking for in the bug report, of course, all the code of check_network() function would have to be implemented.
