I disagree with this. The existing message is much clearer to the
non-root mortal user that gets it and, IMO, it's clearer for the
message to be sent to stdout with the rest of the output from the
scan.
As for errors other than EPERM, well, exactly what other errors *can*
that call return in ifconfig?
What problem are you guys trying to solve?
