I think I've found one item so far that requires udev. My laptop's graphics chip needs a binary blob from radeon-ucode. That binary blob, in turn, requires the presence of /usr/lib/libudev.so.0 which is a symlink to /usr/lib/libudev.so.0.9.3 (which is also required). I can emerge udev move or copy the 2 files over to /root unmerge udev move or copy the 2 files from /root to /usr/lib/ and it still works. Note that /usr/lib/ is a symlink to /usr/lib64 on my 64-bit gentoo. -- Walter Dnes
