linux - systemctl disable name.service 在重启后不会持续存在

Question

我正在尝试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:

sudo systemctl 停止蓝牙服务

然后禁用它:

sudo systemctl 禁用蓝牙服务

检查:

sudo systemctl status bluetooth.service

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

但每次我重新启动它都会重新打开，我找不到任何人在线提示 systemd disable 命令不像我的情况那样工作

即使在 ubuntu wiki 上它也说它应该工作我做错了什么？

https://wiki.ubuntu.com/SystemdForUpstartUsers

这是我运行这些命令时的输出

Answer 1

也许该服务是由依赖项启动的。有一个 third level of "off" with systemd你可以试试，叫做“掩蔽”:

systemctl mask bluetooth.service

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