使用提示自动 apt-get 安装 dnsmasq

Question

我想自动安装 dnsmasq，但是当我 apt-get install 它时，它提示我回答一个问题，因为已经存在 /etc/dnsmasq.conf。就我而言，我不想更换它。

我怎样才能使它自动化，这样它就不会阻止我 apt-get install 等待用户输入？

# apt-get install dnsmasq -y

 ==> File also in package provided by package maintainer.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.

您可以通过指定 dpkg 选项来自动执行此操作，如下所示：

$ apt-get -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" install dnsmasq -y

这将保留当前的配置文件。
