Since there is no ubuntu release where the newer systemd might be directly used with a kernel older than 5.8, this can only reasonably happen in a container on a older ubuntu release. For example, on a focal release with the 5.4 kernel, a hirsute container can be created, and when it starts up the host dmesg will log the kernel error messages shown above. Note that if using a lxd container, as there is a bug where lxd prevents mounting any fs (which mostly breaks systemd), you must set the 'security.nesting' parameter for the lxd container, e.g.: $ lxc launch ubuntu-daily:hirsute test-h $ lxc set config test-h security.nesting true Note that this hasn't been fixed upstream, and as it's purely cosmetic, it's possible it won't get fixed upstream.
