@jbz That article is named "Jails vs LXC" but really compares Docker with Jails. Docker and LXC are two different animals. While it's true that LXC containers do use namespaces and cgroups, they don't need container runtimes like runc, containerd, etc. They also don't need OverlayFS (the article is incorrect in this regard). LXC is more like FreeBSD Jails than Docker.
