如何停止systemd-logind并且以后不被激活？

Question

我想知道如何停止 systemd-logind 并且稍后不重新启动或激活？

我知道 systemd 服务单元文件有一个参数： restart= ，当它的值设置为 no 或 on-failure 时，停止此服务，例如systemctl stop xxx，此服务将不会重新启动或激活

但是 systemd-logind 看起来很特别？我有点不解

I #systemctl cat systemd-logind

要停止正在激活的服务，正确使用的命令是systemctl mask ...。这也将防止它在启动时启动。

如果您只想阻止它此刻启动，请使用systemctl mask --runtime. 这意味着当您关闭或重新启动时，设置将被忘记。

logind 非常重要，我预计会中断启动或登录 - 手头有一个救援磁盘并知道如何使用它:)。
