Disabling GNOME Tracker and Other Info

GNOME's tracker is a CPU and privacy hog. There's a pretty good case as to why it's neither useful nor necessary here: http://lduros.net/posts/tracker-sucks-thanks-tracker/

After discovering it chowing 2 cores, I decided to go about disabling it.

Let's say you have a SysV Init Script named foo

1. Copy the file to /etc/init.d/foo

2. Enable the SysV service: chkconfig --add foo

3. Enable the SysV service: chkconfig foo on

4. Start the service: service foo start. After this, systemd-sysv-generator will generate this file /run/systemd/generator.late/foo.service, copy this file to /etc/systemd/system by running: cp /run/systemd/generator.late/foo.service /etc/systemd/system/foo.service

5. Edit /etc/systemd/system/foo.service by running systemctl edit foo.service, add in the following line to foo.servie (this makes the service installable)

【译】Docker 和 S6 ——我的进程管理器新欢

点击这里阅读原文。

在我之前的博文中，我描述了我是如何在容器中使用进程管理器的，并做了一些展开。但我还是觉得有必要针对 Laurent Bercot 开发的 S6 做更详尽的说明。

什么用 S6 而不是 Supervisor？
