David,

Not bug, feature....  <big grin>

kudzu launches netconfig.  netconfig by definition is an overwriting
operation.  It writes the
/etc/sysconfig/network-scripts/ifcfg-<interfacename> with the first two
fields.  It writes the /etc/sysconfig/network with the gateway.  It
writes the /etc/resolv.conf with the name server.

HTH,
