[clue] [Tech] Red Hat init scripts

[Dan Kulinski]

I apologize, I messed up my explanation on a critical part of this.  K
scripts are also run when entering that runlevel, not at exit.  You want to
have your K script in the shutdown runlevel (runlevel 0) and the reboot
level (runlevel 6).

I always convince myself of the way it should work and then look at my
system to verify.  I need to reverse that order.
