Package: debian-podman-config-override
Version: 2.1
Severity: normal
X-Debbugs-Cc: void@rittich.net

I was setting up a minimal installation of chimaera to test the new 
`debian-podman-config-override` package. On this system, running a 
simple container with podman fails.

    $ podman pull docker.io/dyne/devuan:beowulf
    ...
    $ podman run -ti --rm devuan:beowulf
    Error: OCI runtime error: invalid file system type on '/sys/fs/cgroup'

I had not seen this error message when testing the configuration that is 
now in `debian-podman-config-override`. When testing earlier, I was 
running a full desktop installation, and it turns out that `elogind` 
mounts the cgroup filesystem. Thus, installing `elogind` and restarting 
allows podman to run.

Instead of `elogind`, it is also possible to install `cgroupfs-mount` or 
`cgmanager`. Maybe there are more packages that mount the cgroup filesystem.

To improve the out-of-the-box experice of chimaera, I would suggest to 
make `debian-podman-config-override` to depend on a package that mounts 
the cgroup filesystem. I would suggest to make the package depend on 
`cgroupfs-mount`. It would be possible, however, to just require that 
any of the above-mentioned packages is installed.

Yes, I think allowing any is the way to go which should provide the greatest
flexibility.

I note that cgmanager is not present in debian bullseye or later so appears to
be on its way out[1]. The best solution is probably to depend on (or recommend?)
elogind | cgroupfs-mount | cgmanager.

Sounds good. I would say, recommending is enough, because if the user 
wants they can still mount cgroupfs manually.
