 Perhaps I should describe my application.
 
 I wish to configure a tun device at boot with an IP address and chown the
 corresponding /dev/tun file to the userID that will use it running
 Hercules.  The other end of the tunnel is an IBM System/360
 channel-to-channel adapter.
 
 I would like to be able to restart Hercules without having to issue
 commands (or ioctl()s) that require root privileges.
 
 Hercules ships a setuid program, hercifc, to set interface parameters by
 ioctl().  I am required to be rid of this trojan horse.
 
 Thanks,
 
    j.
