podman: Unable to run `podman pod create` on systems without systemd installed.

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

When attempting to run podman pod create on systems without systemd installed, such as on a system with OpenRC as the init system, podman errors with unable to create pod cgroup for pod. Setting cgroups-manager to cgroupfs and systemd to false in containers.conf does not fix the issue.

Steps to reproduce the issue:

Run podman pod create as root on OpenRC system

Describe the results you received:

Error unable to create pod cgroup for pod ... The name org.freedesktop.systemd1 was not provided by any .service files

Describe the results you expected:

cgroup creation using cgroupfs/related tools rather than systemd

I’m having a similar issue on a Devuan GNU/Linux 4.

I installed podman by simply using the apt package manager:

apt install podman

I tried to setup the /etc/containers/containers.conf as mentioned above (it didn’t exist, I created it), without much success:

 # root@latitude: ~ < 2023_06_18__12:00:36 > [bashpid_5652 25]
podman run -dt -p 8080:80/tcp docker.io/library/httpd

Maybe I’m missing something?
