sys-fs/udev-197, 200, 204. --- will install to / instead of /usr so it 
will work with sep. /usr just like eudev does, or just like udev-171 used to

basically the only thing to look out for is the network interface names, 
you can add extra entry to grub that boots with net.ifnames=0 kernel 
parameter, or create empty file /etc/udev/rules.d/80-net-name-slot.rules 
if you don't like the new names
