16. 通过 systemctl start upower.service ，启动会被系统强杀 SIGSYS ( syscall=12 )，apport.log 会提示下面的错误
```shell
ERROR: apport (pid 3268) Thu Sep 15 10:25:01 2022: host pid 3257 crashed in a separate mount namespace, ignoring
```
journalctl -xf 会提示下面的错误
```shell

```
单独执行 /usr/libexec/upowerd -v ，也能成功执行。这个问题让我困惑了好久，目前找到解决方法了；我们需要做的是把 upower.service 里面的几句话注释掉即可
```shell
# System call interfaces
LockPersonality=yes
SystemCallArchitectures=native
SystemCallFilter=@system-service
SystemCallFilter=ioprio_get
```
猜测这样可能就不会启动 seccomp 的功能了，upower.service 调用的系统调用就能正确进行了，保证 systemctl start upower.service 启动成功
