ping is installed suid root on most (all?) linux systems, since it also
requires root access to open raw sockets and send ICMP packages. That
doesn't really matter, however, since the interface's routing table also
needs to match the destination IP, and what good would it do to have two
different interfaces in the same subnet that aren't bonded?
