Comment 6 for bug 16473

Below is my /etc/network/interfaces, which is as-generated by a pre-Hoary
install, dist-upgrade to Hoary through Breezy. I've only changed ath0 to DHCP
recently (previously it was iface ath0 inet manual, no options), and after doing
this, lo ends up down with no IP, at boot. It's been suggested that this bug is
at fault. Either way, it really f**king bites, and breaks your system in a
very, very non-obvious way.
