I'm seeing similar (probably the same) issue with klibc ipconfig
failing to obtain DHCP address. Due to this, I cannot boot NFS-root
system using newly-generated initrd image.
I have recompiled ipconfig with -DDEBUG=1, and it seems ipconfig
is failing to use DHCP OFFER response from the server. I tried
both source from 'git' and 'apt-get source (of klibc_1.5.18-1)'.
I have attached debug output of ipconfig and tshark dump taken
at DHCP server. Hope this helps to resove the problem.
Best Regards,
Taisuke Yamada

Running as user "root" and group "root". This could be dangerous.
