As I said earlier, if you are looking for these system shutdown commands,
use:
systemctl reboot
systemctl halt
systemctl poweroff
directly. The "halt, "reboot", and "poweroff" commands are only there for
backwards compatibility.

So fix it, no change to systemctl is needed AFAICT, just replace the
symlink with a tool that does "the right thing", probably running
"poweroff" passing all arguments verbatim. Don't forget to fix the
manpage as well.
