网卡识别问题

我把做好的LFS系统，移到一台工控机上，工控机一个4个网卡，e1000的。以前在RH9上，对应的很好，eth0-4.
但是换了LFS以后，顺序都乱了。变成了eth2-5，这个是为什么？应该真么调整，谢谢

显示如下：
root:~# ip addr sh
1: eth3: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:90:0b:09:d7:a4 brd ff:ff:ff:ff:ff:ff

2: eth2: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 100

看 LFS 手册后面部分，做规则文件。

LFS手册上有,7.13.1. Creating stable names for network interfaces
