Separate from the problem, I notice that this is not inline with the
book as we use bind mounts of the host's VFSs. On first glance, I think
it should work, but am unsure (especially since the problem seems to be
in /dev which does work). On that, does /dev/urandom exist on the host?
I typically work from SSH until a system is complete. Here is my simple
lfs-chroot.sh script for comparison, which accounts for the already
mounted VFSs, since I might have multiple sessions open to the same host
- note that this does not account for ending the first session in early
(there is probably a way to check for that, but this works well enough
for me):
dj@lfsdt2 [ ~/LFS/LFS/trunk ]$ cat ~/bin/lfs-chroot.sh
#!/bin/bash
export LFS=/media/lfs
FIRST_IN=0
mount | grep "${LFS}/dev" && FIRST_IN=1
if test "${FIRST_IN}" == "0"; then
sudo mount --bind /dev "${LFS}/dev"
sudo mount --bind /dev/pts "${LFS}/dev/pts"
sudo mount --bind /dev/shm "${LFS}/dev/shm"
sudo mount --bind /proc "${LFS}/proc"
sudo mount --bind /sys "${LFS}/sys"
sudo mount --bind /run "${LFS}/run"
fi
sudo chroot "${LFS}" /usr/bin/env -i \
HOME=/root TERM="$TERM" \
PS1='(lfs chroot) \u:\w\$ ' \
PATH=/bin:/usr/bin:/sbin:/usr/sbin \
SSH_CLIENT="${SSH_CLIENT}" \
/bin/bash --login
if test "${FIRST_IN}" == "0"; then
sudo umount "${LFS}/run"
sudo umount "${LFS}/sys"
sudo umount "${LFS}/proc"
sudo umount "${LFS}/dev/shm"
sudo umount "${LFS}/dev/pts"
sudo umount "${LFS}/dev"

unset LFS
This is what I use:
http://www.linuxfromscratch.org/~bdubbs/basic-blfs-book/starting.html
And a corresponding
$ cat umount-virt.sh
#!/bin/bash
function unmount
{
if mountpoint $LFS/$1 >/dev/null; then
$SUDO umount $LFS/$1
echo $LFS/$1 unmounted
else
echo $LFS/$1 was not mounted
fi
}
if [ $EUID -ne 0 ]; then
SUDO=sudo
else
SUDO=""
fi
if [ x$LFS == x ]; then
echo "LFS not set"
exit 1
fi
unmount run
unmount sys
unmount proc
unmount dev/pts
unmount dev
unmount usr/src
unmount boot
unmount home
