[Bug 972849] [NEW] 12.04 impossible to set manual dns in /etc/network/interfaces when bind is installed

[Saivann Carignan]

Public bug reported:

Ubuntu 12.04 Beta 2 Server
resolvconf : 1.63ubuntu11
network-manager : not installed

When setting manual dns servers in /etc/network/interfaces, they are
always overridden by 127.0.0.1 in /etc/resolv.conf when bind is
installed. Which makes it impossible to set manual dns servers. This
becomes a serious issue when bind is configured to be authoritative and
not recursive for the use on a web server for instance.

If bind is uninstalled and that the computer is rebooted, resolvconf
correctly uses the values in /etc/network/interfaces . If bind is
reinstalled and that the computer is rebooted, resolvconf put 127.0.0.1
again in resolv.conf

/etc/network/interfaces :
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.1
