Bug#243543: /etc/network/interfaces - no loopback interface

[Christopher Martin <christopher.martin@utoronto.ca>]

Package: netcfg
Version: 0.54

(not sure about the exact version of netcfg I installed with, but the 
issue occurred with both beta2 and beta3)

With both beta2 and beta3 I managed to obtain a system with 
no entry for the loopback interface in /etc/network/interfaces.

I went through the netcfg process of the installer. DHCP failed to obtain 
a connection, since it's pppoe, and I wound up punching in 192.168.0.1 
(or was it 127.0.0.1? I can't recall) and other dummy static information 
just to pass through the prompts. I then rebooted, and noticed that 
the /etc/network/interfaces file contained only:

# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.

...but nothing more. That there was nothing present about my fake static 
connection I couldn't care less about, but the lack of an entry for the 
loopback interface is serious. Presumably "lo" isn't missing for 
everybody, or this would have been fixed ages ago, so I guess it must be 
a problem specific to how I handled the installer.

Thanks,
Christopher Martin
