+command you are running inside the container is **systemd**, **/usr/sbin/init**,
+**/sbin/init** or **/usr/local/sbin/init**.

+Running the container in systemd mode causes the following changes:
+
+* Podman mounts tmpfs file systems on the following directories
+ * _/run_
+ * _/run/lock_
+ * _/tmp_
+ * _/sys/fs/cgroup/systemd_
+ * _/var/lib/journal_
+* Podman sets the default stop signal to **SIGRTMIN+3**.
+* Podman sets **container_uuid** environment variable in the container to the
+first 32 characters of the container id.
This allows systemd to run in a confined container without any modifications.
