Databricks uses LXC as container platform. Howevr, the problem is best described in Podman manual page at https://github.com/containers/podman/blob/main/docs/source/markdown/options/systemd.md.

Without LXC doing some ground work first by mounting tmpfs, running systemd init as PID 1 isn't possible. This can easily be achieved on a personal workstation. Doing the same on Databricks isn't possible as I understand it and that's the reason I asked.

To repeat: This functionality exists if choosing to run Databricks provided container.
