我刚刚安装了 Arch Linux，每当我尝试关闭我的电脑时，它都会重新启动。我见过很多类似的问题（这里）但他们的解决方案都不起作用。另外，我有一种感觉，我面临的问题有所不同。因为 systemd 正在发送重启命令。我已经尝试过：
- 不同的关机命令：
shutdown now -h、systemctl poweroff、systemctl --force poweroff - 禁用网络唤醒/类似选项
- 杀死 X 并尝试关闭
事实上，我注意到在系统“关闭”之前，终端会打印该行Started Reboot.我刚刚发现这个问题已经讨论过了这里，但是没有人提出解决方案。下面是我的部分内容journalctl -b 1，您可以修改这些行：systemd-reboot.service：成功并开始重新启动接近日志的末尾。有人能帮我吗？

答案1
对于关闭，你似乎混合了时间和选项顺序
shutdown [OPTIONS...] [TIME] [WALL...]
所以我希望你的命令shutdown now -h给出“-h”作为关闭消息（但在我的系统上它仍然会导致断电......但这可能可以改变。因此尝试
shutdown --halt now
为了更好的效果。简短的形式（在我的系统上是--halt不-H被-h识别的。
然而，这一切可能不是问题，而是内核设置由于一些硬件细节，需要由 grub 传递：
