Yes, I agree. But remember udev is so very young and not perfect.
We worked hard on more important features the last weeks, so this was
simply not handled.
I will post a patch tonight, that extends klibc_fixups.* which is able
to parse /etc/passdw, /etc/group. It already works on my box.

So just wait a few hours :)
