Describe the issue: systemctl command be wrongly translated as sysctl

Suggestions for improvement: fix as systemctl . command names should not be translated.

Additional information: 
en-US version:
The chkconfig tool shows only SysV services and run level information, and may output misleading information. Red Hat recommends using the systemctl command instead.
wrong zh-CN version:
chkconfig 工具只显示 SysV 服务及运行级别信息，并可能给出一些误导信息。Red Hat 建议您使用 sysctl 命令。
