This containerization and virtualization thing is repeated without evidence. There is nothing systemd specific to running containers. Containers and VMs work perfectly well on Alpine, Gentoo and any distribution. Namespaces and cgroups are provided by the kernel. Any init system can use them. Cgroups are mounted at /sys/fs/cgroups and while there continues to be some friction on how these are mounted and used with systemd going its own way, other init systems like openrc manage them perfectly well. The rest of it is standard networking, mounts and autostart services started by the container managers like LXC, Docker, libvirt for VMs and these can be done by any init system.
