I guess that's the answer I was looking for.... no real need to do a 
"vgchange -an" at shutdown.  I was sure that it was not healthy for LVM.
But if it doesn't matter, then I'll just take out the shutdown command.

BTW, if the VG _isn't_ shut down, what happens to it, ie it was active,
then it's suddenly activated again on bootup.  Doesn't sound like clean
functionality to me.

BTW, the finitrd sounds like a cool thing.  I think I'll stick with
simplicity right now (assuming it's safe).
