Thanks. We don't use an initrd in LFS (though there is a hint about how to use one). If you have configured your kernel with CONFIG_DEVTMPFS_MOUNT=y then the kernel will mount a devtmpfs filesystem on /dev and populate it with all the devices it knows about early in the boot process and then udev will take over when it gets started. Otherwise everything in /dev is created by udev when its bootscripts are run (or when you plug the device in if it's something like a USB stick).
