OK, that's what I thought from reading the /etc/rc.d/rc script, but
there's so much gibberish about Red Hat init scripts out on the web that
I felt like I had to double check somewhere reliable.

I still can't tell why the script has 4 'S'-script links, and no
'K'-script link, but the lack of a 'K'-script explains why the lockfile
existed through the shutdown and reboot.  /etc/rc.d/rc0.d/K97script.sh
never got called, and that's the place where lockfile deletion happens.
