It sounds to me, as if you want something like UML... :-)

chroot environments are traditionally quite minimal, meaning that they
usually don't require /dev/pts, /proc, etc.

One approach that I have seen taken, is for privileged information to be
queried through a non-chroot'ed process by the chroot'ed process.
