Bug#2994: "rmmod" doesn't return bad status on failure

[bruce@beagle.pixar.com (Bruce Perens)]

Package: modules
Version: 1.3.69f-2
Maintainer: Michael Meskes <meskes@informatik.rwth-aachen.de>

As you can see in the typescript below, the "rmmod" program returns 0
when it fails to remove a module. "modprobe -r" returns -1, but does not
print the error message. I would like to have one command that I could
use in the "modconf" script that returns bad status if removal fails
_and_ prints the error message.

	Thanks

	Bruce
