dbus-broker not working in Podman container

Description:

The dbus-broker service fails when running Arch Linux in a Podman container with init as root process inside the container. This occurs in the current version (package version 36-4).

I believe that this issue is specific to Arch Linux, as the dbus-broker works in an image based on Ubuntu Oracular (upcoming 24.10 release), which uses the same version (36-1 in their package versioning scheme).

Steps to reproduce:

Install Podman and ensure correct subuid setup
Update the archlinux image: podman pull docker.io/library/archlinux
Start the container with init as the root process: podman run --rm -d --name dbus-test docker.io/library/archlinux /usr/sbin/init
Check if dbus-broker is running inside the container: podman exec dbus-test systemctl status dbus-broker

Expected result:

The status of dbus-broker.service is reported as Active: active (running)

Observed result:

The status of the unit is Active: failed. Full systemctl output:
