This is interesting. We may have to look into a way for the shutdown
process to get runlevels without using utmp. Perhaps init could write
the runlevel directly to a file, such as /var/run/runlevel to work
around situations like this.

If I'm not mistaken, the reboot command is just a link to the halt
binary. So I'd still like to find out if using shutdown will work where
halt/reboot fail.
