Avoid kudzu to re-generate ifcfg-eth0 in FC6 ?

[Steven Shiau]

Hi,
If I replace a network card, the kudzu will re-generate the
/etc/sysconfig/network-scripts/ifcfg-eth0, like:
----------------------
# Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp
HWADDR=00:30:1b:xx:xx:xx
----------------------
How can I disable that, i.e., I do not want to let kudzu automatically
generate the ifcfg-eth0 for me,  while still let kudzu to detect all the
hardware ?

Thanks in advance.
