Subject: bug#595: podman: Podman fails to run containers in the default configuration

Package: podman
Version: 3.0.1+dfsg1-3+b1
Severity: normal
X-Debbugs-Cc: [email-masked]

In the recent version, podman defaults to systemd for cgroup management. See
[Red Hat Bugzilla 1768954] and [podman issue 7544]. Thus, running podman
without changing the configuration on Chimaera results in a dubious error
message.

Podman can be used when creating a file `/etc/containers/containers.conf`
with the following content:

    [engine]
    cgroup_manager = "cgroupfs"

I would suggest to include this configuration file in the podman package of
Devuan, to ensure a good user experience.

Steps to reproduce:

1.  Install podman.
2.  Run the following commands

        # podman pull docker.io/dyne/devuan:beowulf
        ...
        # podman run --rm -ti devuan:beowulf
        ...
        Error: OCI runtime error: sd-bus call: No route to host

3.  Create the file `/etc/containers/containers.conf` as described above.
4.  Try 2. again.
