kernfs: technically, they are not needed for chroot
Chroot command itself does not require kernel VFS mounted. You can mount /proc, /sys, and /run after entering chroot with "mount -v -t proc proc /proc" etc. For /dev, if the host kernel supports devtmpfs, you can also mount /dev in chroot with "mount -v -t devtmpfs devtmpfs /dev". Even if the host does not support devtmpfs, it's still possible to mount /proc in chroot, then use "mount --bind /proc/1/dev /dev". It's just LFS editors decide to mount them before chroot. So reword some untrue assertions.
