Actually I think it might depend on how the system gets shut down.
Regardless, since you definitely want this to run at shutdown time,
adding the shutdown key word is the right way to go.

Weird. Not that big a deal either way actually, but I'll try to keep
this in mind next time.

You're right, and if there were more than just two spots, or the same
file name was used in more than one script, it would be worth a level of
abstraction. But since neither of those is true, (and since the file
name is very unlikely to change), it's not worth it. Also, FYI, the way
you did it is not the typical "Bourne shell'ish" way to abstract a file
name. It would be much more common (and infinitely more efficient) to
simply set a script variable with the file name, and then use that
throughout the script.

Yes, and I appreciated that at the time, and gave it a cursory review.
At the time I thought, "this is kind of weird, but doesn't look like it
will break anything." :) It was only after it stopped working for me
that I started digging into it more deeply, and then I figured if I'm
here already, might as well clean up a couple more items. Note, nothing
you did is really wrong, and I appreciate your contribution, as I'm sure
the other rc.d folks do as well.
