[Bug 1067043] Re: resolvconf adds an empty "nameserver" record into /etc/resolv.conf

[Thomas Hood]

FIrst, I'd like to know exactly what /etc/network/if-up.d/000resolvconf
is receiving in the IF_DNS_NAMESERVERS variable.  Please apply the
appended patch, down and up the br0 interface, confirm that
/run/resolvconf/interface/br0.inet still contains

    nameserver 66.185.16.130
    nameserver
    nameserver 66.185.16.131

and then post here the lines from /var/log/syslog that look like the
following ones.

Oct 22 22:26:38 myhost /etc/network/if-up.d/000resolvconf: 0000000 2e31 2e32 2e33 2034 2e35 2e36 2e37 0a38
Oct 22 22:26:38 myhost /etc/network/if-up.d/000resolvconf: 0000020

Second, what happens if you comment out the bridge_* options in the iface br0 stanza?  Does the spurious "nameserver" line go away?
