man halt:

>NOTES
>       Under older sysvinit releases , reboot and halt should never be called directly. > From release 2.74 on halt and
>       reboot invoke shutdown(8) if the system is not in runlevel 0 or 6. This means that > if halt  or  reboot  cannot
>       find  out  the  current  runlevel (for example, when /var/run/utmp hasn't been > initialized correctly) shutdown
>       will be called, which might not be what you want.  Use the -f flag if you want to do a hard halt or reboot.
