Answer
systemd expects full init control and multiple processes, conflicting with container isolation.
Quick Answer
systemd expects to be PID 1 with full access to cgroups, D-Bus, and systemd-specific kernel interfaces. Containers restrict all of these — no cgroup write access, no D-Bus, limited capabilities. systemd inside a container needs --privileged to work at all, which defeats container isolation. Use supervisord or tini instead for multi-process containers.
