This information can be read by the "runlevel" command as well as "halt" and "reboot". Having the information logged in /var/run/runlevel as well as the utmp file means systems without utmp (like those running the musl C library) can still check the current runlevel. This is useful when running halt/reboot as these programs want to check the runlevel. Updated the changelog, and manual pages for halt and runlevel.
