User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.4.10 i586)

Description of problem:
Upgrade from 7.1 to 7.2 which an existing working 2.4.13 kernel. When
booting after the upgrade eth0 fails to get assigned an IP address, default
route is not set etc. have traced this down to the ifup script is using a
different command, ip instead of ifconfig, to setup the device. After the
system boots the device can be setup correctly using ifconfig with
appropriate options.

The root problem seems to be that a kernel compiled without the netlink
socket option under networking options causes the ip command  to fail.
Recompiling with the netlink socket enabled the ip command works and
network is setup at boot time. ifconfig works regardless of the netlink
option, 7.1 script was using ifconfig to setup the device.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. configure kernel without netlink socket
2. boot new kernel
3. watch error messages regarding lo, eth0
	

Actual Results:  same as above

Expected Results:  networking should setup correctly on system boot.

Additional info:

script should have some fall back to use ifconfig if ip command fails.
