hmm, unstable got newer klibc innbetwen, 1.5.17 should fix most of
the listed pain, although 1.5.18-1 would be recommended, just uploaded.

with latest initramfs-tools from unstable default is DEVICE=""
which means it picks up any ethX

yeah well, man initramfs sort of has pointers in the direction of
linux-2.6 sources. now latest libklibc shipps README.ipconfig

fixed.

thanks for your feedback, looking forward to test against newer klibc.
