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

I'd like to see if you can still reproduce that with latest klibc!?
it should no longer be the case.

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.
