While it doesn't have to, it really makes sense to. If you run anything
like udev, having it bind mounted makes a lot of sense.
Exactly. Only if you have a static /dev you have no need to bind mount it
(but you do need to keep it in sync anyway, when devices get created or
modified). Otherwise, things may work almost ok, but there is always the
possibility that devices in the real /dev and in the /dev inside the chroot
jail get out of sync, which in turn may result in wreaking real havoc: think
"I thought I was formatting my usb pen and formatted my external usb hard
disk instead"... Bind mounting /dev just ensures the two are always in sync,
eliminating this kind of problem.
