Bug#1065573: kxc: initramfs script writes a line to resolv.conf with $IPV4DNS0 even if empty

Package: kxc
Version: 0.15-4.1+b1
Severity: important
Tags: patch

Dear Maintainer,

The script
/usr/share/initramfs-tools/scripts/init-premount/kxc-premount-net writes
a line to /etc/resolv.conf adding a "nameserver $IPV4DNS0" even if that
environment variable is empty. If I understand correctly that variable
is only set if a DNS is passed via the ip= kernel parameter. Popular
simple configurations like ip=dhcp will then have no DNS server set
there, which will end up with a bad /etc/resolv.conf line with
"namesever ".
