关于 /dev/urandom 的流言终结
我觉得没必要，但如果你真的要用 /dev/random 来生成 “长期使用的密钥”，用就是了也没人拦着！你可能需要等几秒钟或者敲几下键盘来增加熵，但没什么问题。但求求你们，不要就因为“你想更安全点”就让连个邮件服务器要挂起半天。

不要安装 Yaourt！在 Arch 上使用以下这些替代品。
AUR是一个为 Arch 用户而生的社区驱动软件仓库。Debian/Ubuntu 用户的对应类比是 PPA。AUR 包含了不直接被 Arch Linux 官方所背书的软件。如果有人想在 Arch 上发布软件或者包，他可以通过 AUR 提供给客户。这让末端用户们可以使用到比默认仓库里更多的软件。
