But containers are not just chroot + marketing. Some containers offer real security advantages not found with using straight up chroot. I would agree that the __basis__ of containers is chroot however.

Any search of "chroot vs docker" or "chroot vs lxc" will immediately show that there are some attempts made to isolate the container from the host.

But I will say that I use docker images on a regular basis in chroots for the simple fact that I don't have to wait for debootstrap (or similar) to build a chroot for me.
