You can easily create a base Debian system using debootstrap. To have a usable chroot environment, you'll also need to mount both the dev and proc filesystems. Follow these steps to create a chroot environment in Debian.
Steps to create a Debian chroot environment:
- Create a directory that you want to use for the base system (chroot-debian in this case).
- Create a base system using debootstrap.
sudo debootstrap sid chroot-debian http://mirror.pacific.net.au/debian/
You can change sid to stable to use the stable distribution, and to use Debian mirror closer to your physical location for faster download speed.
- Mount proc and dev filesystem.
sudo mount -o bind /dev chroot-debian/dev sudo mount -o bind /proc chroot-debian/proc
- Start chrooting.
sudo chroot chroot-debian /bin/bash
- Once done, exit the session and don't forget to unmount the dev and proc filesystem.
sudo umount chroot-debian/dev chroot-debian/proc
