sorry, I hit the button too early. I meant: is it OK? Is it all I
should do? It turns out it isn't. The script isn't executed at boot.

So now the (general) problem is: What is the proper, current way to
make Fedora 16 run a shell script at boot time, possibly before X
starts, as the last script otherwise? The online documentation is
surprisingly lacking on this.
