EL6 used SysV based init and runlevels, EL7 & EL8 use systemd targets. If you look at the halt and shutdown commands they are symlinks to /usr/bin/systemctl now and they are implemented as shims that replicate the effect of the old SysV processes. So the following have the same effect: "systemctl isolate halt.target" "halt" "shutdown -H now" "systemctl halt" there are equivalents for "poweroff" and "reboot" as well. P.
