Very sensible. Many people can forget the chroot completly and just

You only need a few files from /etc and they don't tend to change. For
example you need the /etc/hosts file. I always copy them over.
As for /dev you can bind mount thart or have a static version
there. You will need /dev/pts though for anything using pseudo ttys.
Last there is /sys. A very few things need that.
