“关键：我们失败了，但失败的鲸鱼已经死了。抱歉……”

Question

当我今天启动我的机器时，我在我的系统日志中收到了一些非常奇怪的消息：

...
Aug 17 18:58:15 Floral-Towel systemd[1349]: Startup finished in 266ms.
Aug 17 18:58:15 Floral-Towel systemd[1349]: Starting Default.

Aug 17 18:58:17 Floral-Towel systemd[1349]: Stopped target Basic System.
...

我包括了当时的一些其他信息，以防万一它们可能对您有所帮助。但要切入正题，谁或什么是“失败的鲸鱼”？为什么他/她/它死了？这一切的意义是什么？它在我的系统日志中做什么？

我正在运行 Ubuntu Gnome 15.04、Gnome Shell 和 Gnome 3.16。

在这种情况下，如果出现问题，“失败鲸鱼”是由 GNOME 记录的错误消息。它以Twitter 用来显示错误的Yiying Lu的插图命名。

如果它已死，则意味着没有足够的 GNOME 运行来显示错误。
