You don't need that, unless you want the changes made in
the chroot/dev to show up outside of the chroot.

Just initialize the device nodes in chroot/dev, they will
work just fine there (the kernel uses the device numbers,
not the path).

Presuming a bare busybox in chroot/bin - (/opt/test/bin)
Here is the short version:

mount -t proc proc /opt/test/proc
mount -t sysfs sysfs /opt/test/sys
chroot /opt/test /bin/busybox sh
/bin/busybox --install -s
mdev -s

Your done.  Have fun.
