[Bug 1094533] [NEW] all entries on dns-nameservers line not being processed

[Kevin Otte]

Public bug reported:

According to the manual page for resolvconf, multiple nameservers may be
specified in a single dns-nameservers directive. When I try this, I am
only getting the first entry on the line:

(full interfaces file available on request. This is the only stanza with dns-nameservers directives though)
root at atlantis:~# head -n 8 /etc/network/interfaces 
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback
    dns-nameservers ::1 127.0.0.1
    dns-search home.nivex.net nivex.lan

root at atlantis:~# cat /etc/resolv.conf 
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver ::1
search home.nivex.net nivex.lan

root at atlantis:~# for F in /run/resolvconf/interface/* ; do echo === $F === ; cat $F ; done
=== /run/resolvconf/interface/lo.inet ===
search home.nivex.net nivex.lan
nameserver ::1
nameserver 127.0.0.1
=== /run/resolvconf/interface/lo.named ===
nameserver 127.0.0.1


I unfortunately need both v6 and v4 nameservers because some programs (notably mtr, bug on file) fail without the presence of a v4 nameserver.
