The invocation that's always worked for me is<br>
<br>
shutdown -h -P<br>
<br>
which halts and powers off.<br>
<br>
And then I discovered "poweroff" which is much easier to type and<br>
remember.<br>
<br>
But /sbin/poweroff just seems to be a soft link to /bin/systemctl<br>
There must be some command line detection in systemctl to determine<br>
how it was invoked, and then to take different actions depending on<br>
the command used.<br>
