dhclient-script NFS errors with busybox ifconfig

[John Faith]

Hello!

I am trying to use dhcp-3.0.3b1 on an embedded Linux board (kernel 
2.4.20) with a NFS root filesystem.  The 'ifconfig' on this system is 
from busybox 1.01.

When I run 'dhclient' as root, I get NFS errors and my filesystem goes 
away.  I've tracked it down to line 94 in dhclient-script (which is the 
same in dhcp-3.0.4b3.tar.gz):

     ifconfig $interface 0 up

I can run 'ifconfig eth0 0 up' by hand, and it completes without 
printing an error, but subsequent commands fail due to the NFS 
filesystem going away.

Has anyone else run into this with busybox ifconfig, or know if this is 
a dhclient-script bug or a busybox bug?


Thanks!
John
