Just make sure to create these directories.

Or you bind-mount the root file system to somewhere else, this gives you the
original system without the things mounted on top of it:
mount -o bind / /mnt
cp -a /mnt/dev /newroot/
Or create the device nodes by hand, it's only two that are needed for udev
to come up:
mknod -m 660 /newroot/dev/console c 5 1
mknod -m 660 /newroot/dev/null c 1 3
I _think_ you also could just copy the populated /dev, but I like to have
only the necessary things in there, not everything that udev creates.
