I make periodic backups of my laptop where I use some podman containers.
To perform a backup I just invoke rsync to copy my /home/xxxx/.local/share/containers
directory to nfs mounted filesystem.
Containers are running, but quiescent, no real activity occurs.
Is this a correct way to back up or is there anything special about
container directory to be taken into account? As far as I understand
some hash-named subdirectories are shared between different containers
and images using special kind of mounts, can this lead to duplicate
copies r inconsistencies?
Underlying fs is btrfs.

There is somthing warning, when I add "--pid=host".
How can I get this warning gone?
[rsync@rsyncdk2 ~]$ podman run --rm --pid=host fb7ad16314ee sleep 3
WARN cannot toggle freezer: cgroups not configured for container
WARN lstat : no such file or directory
I have 2 node in cluster, node1 and node2. They share the same HOME directory with lustre.
If I run a container on node1, it will take some record in ~/.local/share/containers/storage/overlay-containers. And run in /run/user/1000/containers.
But on node2 there is not /run/user/1000/containers. Because of share HOME directory, there is ~/.local/share/containers/storage/overlay-containers on node2. So there is some error on node2.
How could I redirect ~/.local/share/containers/storage/overlay-containers to the local directory on node1 and node2?
I built a container that mounts the /home directy (it has one
(I used buildah and podman on that unprivileged account, using rhel8)
However when I connect to the container, I see that the unprivileged
user's home directory is owned by root.
any idea why that would be, I am probably missing something
39 hours from now, on Thu April 21, 2022 at 11:00 am EDT (UTC-5),
we'll be holding the next Podman Cabal meeting. At the moment only one
topic on Contribution policies in GitHub. Happy to take more topics!
Agenda with video link here:

The OS is oracle linux 8 with
I start a container in a systemd service using:
+ /usr/bin/podman start cloud-dice
And get this error from podman:
Error: unable to start container
failed to mount shm tmpfs
And these messages in dmesg:

If I rebuild the container then I do not see the tmpfs error and
What do I need to do to fix the "tmpfs: Unknown parameter 'context'"
error that I'm assuming is root cause?
The next Podman Community meeting is happening in just under 24 hours,
on Tuesday, Apr 5, 2022, at 11:00 a.m. EDT (UTC-5). The agenda is still
a WIP with room for topics. The Agenda with video link here:
Hope to see you there!
Dear Podman maintainers,
We are a group of four computer science Master's students from the Delft University of Technology in the Netherlands following the course IN4315 Software Architecture ( https://se.ewi.tudelft.nl/delftswa/). We chose Podman as the open-source project that we would study, analyse and contribute to.
Over the last 8 weeks, we have published our research in 4 essays, which you can find at https://desosa2022.netlify.app/projects/podman/. On this page, you can also find a list of PRs we made.
It has been a pleasure to work on the contribution to Podman. We enjoyed and learned a lot from this process and we want to thank you for the guidance and assistance you provided us.
We are eager to know what your thoughts are on our research. If you have any thoughts or feedback on our work that you would like to share, we would be excited to hear them. We would also like to inquire if there are any job/internship opportunities available for us in the future.
Thank you for your time and consideration. Feel free to reach out to us through email or GitHub for anything you would like to discuss.
