Is there a popular project which puts systemd and multiple processes in a container? I've seen only single process containers so far.

LXD/Incus for hypervisor-for-containers use-case.

Podman for "like Docker, but made by Linux people". It supports both application containers and system containers (which have systemd as PID 1).
