我生成的 resolv.conf 的内容来自哪里？

我有一个已安装的 Ubuntu 14.10 服务器resolvconf。

在 中/etc/resolvconf/resolv.conf.d/base，我有：

nameserver 127.0.0.1

在 中/etc/resolvconf/resolv.conf.d/head，我有：

# 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

在 中/etc/resolvconf/resolv.conf.d/original，我有：

domain members.linode.com
search members.linode.com
nameserver 207.192.69.4
nameserver 207.192.69.5
nameserver 97.107.133.4
options rotate

我的/etc/resolvconf/resolv.conf.d/tail符号链接到/etc/resolvconf/resolv.conf.d/original。

为什么我的resolv.conf生成是这样的？

# 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 74.207.242.5
nameserver 74.207.241.5
nameserver 127.0.0.1
search members.linode.com
domain members.linode.com
search members.linode.com
nameserver 207.192.69.4
nameserver 207.192.69.5
nameserver 97.107.133.4
options rotate

前 2 行和第四行出自哪里？据我了解，resolvconf应该只使用来自head、base和`tail 的信息。

这是我的/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

# The primary network interface
auto eth0
iface eth0 inet dhcp
