我安装了 Linux Mint 18.3，并对其进行了大量修改。我想更改此安装的名称，这样对于普通人来说，它不是 Linux Mint，而是其他一些奇怪的发行版（原因）。
我已经更改了/etc/lsb-release、/etc/os-release、 以及/etc/upstream-release/lsb-release所有内容以反映我想要的名称。然而，这是我得到的结果：
正如你所看到的，Base System它下面有“Eleftheria 3.0 Meteor”（我要使用的名称），但在顶部它仍然显示 Ubuntu。
我想更改它，以便用户看到不同的操作系统，但系统仍然将其识别为 Linux Mint/Ubuntu，因此我不会遇到应用程序等问题。
这就是我能做的一切吗？或者我可以修改其他内容以反映所需的名称吗？
谢谢！
