文章摘要
这篇文章介绍了`systemd`中一个名为`rc-local`的单位配置文件的设置。它遵循LGPL-2.1协议，说明`systemd`作为自由软件的 redistributable 和可修改性。文章描述了`rc-local`文件如何通过`multi-user.target`自动加载，配置包括`Description`、`Documentation`、`ConditionFileIsExecutable`、`After`等部分。此外，文章还提到该服务类型为`fork`，执行`start`命令，设置`TimeoutSec=0`、`RemainAfterExit=yes`和`GuessMainPID=no`。最后，说明`rc-local`的安装由`multi-user.target`负责管理。
