Bug 556001

Description of problem:
In short:
eth2:BOOTPROTO=dhcp, eth3:BOOTPROTO=static,192.168.3.1. When both have their cable connected, everything works fine, but when eth2 is disconnected, dhclient sets eth3 to ip from dhcp server.

Version-Release number of selected component (if applicable):
dhclient-4.1.0p1-13.fc12.x86_64

How reproducible:
always

Steps to Reproduce:
1.use network service only (not NM), set eth2:BOOTPROTO=dhcp, eth3:BOOTPROTO=static ip=192.168.3.1
2.unplug cable from eth2
3.reboot
  
Actual results:
dhclient sets eth3 to ip from dhcp server after some time. When booting, eth3 has ip 192.168.3.1 for a while, but it reassigned later to ip from dhcp.

Expected results:
eth3 is not altered

Additional info:
doing service network restart fixes eth3's ip.

I have 4 NICs.  eth0 are eth1 disabled (blacklisted kernel module).

eth2 is connected to ISP: DEVICE=eth2, BOOTPROTO=dhcp, TYPE=Ethernet, HWADDR=00:30:4f:71:98:f2, NM_CONTROLLED=no, ONBOOT=yes, USERCTL=no, PEERDNS=yes,
IPV6INIT=no. 

eth3 is connected to LAN: DEVICE=eth3, BOOTPROTO=static, NETMASK=255.255.255.0, TYPE=Ethernet, HWADDR=00:30:4f:71:99:1d, IPADDR=192.168.3.1, NM_CONTROLLED=no, IPV6INIT=no, ONBOOT=yes, USERCTL=no. 

On eth3 there is also my own dhcp server (sysconfig:DHCPDARGS="eth1 eth3").

in chkconfig network is on, NetworkManager is off

boot.log:

eth0:  Device eth0 does not seem to be present, delaying initialization.-- makes no problem, because this line is present also when eth2 has cable plugged in and everything works
