#194214 — How to shut down

What's the current best practice to shut down the system? In the old
days I used to:
# shutdown - h now

but then I read of the systemd way:
# systemctl poweroff

However, with the latter the system does shut down, although the machine
does not power off (I have to physically press the off button). While
with the former it actually powers off.

I'd go with "shutdown" being the best practice, since it does what you
want it to do.

If you *really* want to do things the "systemd way(tm)", maybe the
manpage will have something about actually halting / really shutting off
the power. I wouldn't know though, systemd is far too invasive for my
tastes; and I don't need all the "whizbang features" they claim will
help me out.

Here, 'systemctl poweroff', as user or as root, does power off the
machine, both in stable and testing. So the question is why it does not
work in your case.

That is the question. Yet I'm uncertain whether that question is amenable to
an answer.

I suffer from the same syndrome, no matter the method (shutdown -h now
and poweroff as root, systemctl poweroff as user and root).

The last few attempts with "systemctl poweroff" as root have powered the
machine off (one time as a regular ".homie" user that command produced a
"permission denied" message concerning, if memory serves--and it's
serving less and less as time goes by--journalctl).

It's periodic (well, periodic implies regularity and I've discovered
none). In all cases the shutdown is performed correctly, cleanly, but
sometimes the machine does not power off.

This is a chronic disease for which the only cure might be a bios
update (as I was informed by a kernel hacker here).

BIOS update solved same problem on a decade old HP desktop here last year.

You can use either. `shutdown -h now` on a machine with systemd actually
invokes systemctl with the equivalent of systemctl poweroff[1].

If your machine isn't actually powering off, usually that indicates that
one or more units isn't finishing properly. The output of journalctl
will tell you what is going on in such a case.

Yes, I've checked again and now 'systemctl poweroff' does power off the
machine. No idea on what changed.

FYI:

By default, Ctrl-Alt-Del reboots the machine.
As has been pointed out once in this list (thanks to Michael Biebl),
you can have Ctrl-Alt-Del power off the machine by adding a link
/etc/systemd/system/ctrl-alt-del.target pointing to
/lib/systemd/system/poweroff.target.

# ln -s /lib/systemd/system/poweroff.target /etc/systemd/system/ctrl-alt-del.target

However: if you then keep Ctrl-Alt-Del pressed for a second, the
machine still reboots.
That way, you could use Ctrl-Alt-Del for both poweroff and reboot.
