systemctl disable name.service 重启后不存在

Question

我试图找到一种在启动时在 Ubuntu 16.04 上禁用蓝牙的方法，我一直在网上绊倒的一种方法是使用 systemd

基本上

首先，停止服务：

须藤 systemctl 停止 bluetooth.service

然后禁用它：

须藤 systemctl 禁用 bluetooth.service

查看：

须藤 systemctl 状态 bluetooth.service

https://askubuntu.com/questions/744640/best-way-to-deactivate-bluetooth-on-system-startup-with-systemd-and-not-upstar

但是每次我重新启动它都会重新启动并且我找不到任何人在线抱怨 systemd disable 命令在我的情况下不起作用

即使在 ubuntu wiki 上，它也说它应该可以工作，我做错了什么？

https://wiki.ubuntu.com/SystemdForUpstartUsers

这是我运行这些命令时的输出

Answer 1

也许服务是由依赖项启动的。您可以尝试使用 systemd的第三级“关闭”，称为“屏蔽”：

systemctl mask bluetooth.service

一旦被屏蔽，服务就根本无法启动，即使是手动启动也是如此。您可以稍后“取消屏蔽”它。
