Hello,
So the problem here is, again, linked to the fact that I'm using a test
SELinux policy that doesn't contain all the needed contexts, so yeah
it's a mix of configuration issue and the fact that podman is not
ignoring these errors if SELinux is in permissive. I'll ping upstream again.
So the remaining problem here is iptables command not being installed
(and the seccomp.json file missing to a lower extend)

Hello,
I just did a minimal test VM and... it indeed works...
I'll investigate why on my machine it's not working.
But, on the test VM, podman still fails because "iptables" is not
installed, only "nft" is intalled by default now. So there is still a
problem here.

Hi Laurent,
I've downloaded the Bullseye Alpha 3 debian installer and installed
using kvm to have a super clean new system. Unfortunately, I was
unable to reproduce the issue that you described below. (I did find
some issues with rootless podman outside of a gnome-session, but
that's a different story).
The symptoms sound a lot like described in this upstream bug:
https://github.com/containers/podman/issues/5721
<https://github.com/containers/podman/issues/5721>
Can you please compare your notes with that upstream bug? Can you
confirm that the 'overlay' kernel module is loaded? (in my test, it
was loaded automatically). If you still think this is an issue in the
Debian package, please let me know. I may require your assistance
with reproducing this issue.

Hello,
After installing podman, I cannot run it as root out of the box as it
fails with:
ERRO[0000] [graphdriver] prior storage driver overlay failed:
kernel does not support overlay fs: 'overlay' is not supported
over extfs at "/var/lib/containers/storage/overlay": backing file
system is unsupported for this graph driver
Error: kernel does not support overlay fs: 'overlay' is not
supported over extfs at "/var/lib/containers/storage/overlay":
backing file system is unsupported for this graph driver
Looking at fedora it seems that they have a containers-common package
that ships a default storage.conf file:
https://src.fedoraproject.org/rpms/containers-common/blob/rawhide/f/storage.conf
<https://src.fedoraproject.org/rpms/containers-common/blob/rawhide/f/storage.conf>
I see that the debian package is shipping a file in
/usr/share/containers/storage.conf (in the containers-storage
package),
but that file is apparently not read (strace only shows that the
file in
/etc/containers is read) and anyway unlike in fedora:
1) the driver is not set to overlay
2) the file is installed only if the containers-storage package is
installed, which is not done by default.
3) that file is not read anyway, strace only shows that
/etc/containers/storage.conf is read and not
/usr/share/containers/storage.conf, so the file is apparently useless
Shouldn't debian do the same thing than fedora so everything
works OOTB?
As a side note, I can see they are shipping also other files as well,
like the seccomp.json file, using strace, it seems that podman
tries to
read them:
[pid 14835] newfstatat(AT_FDCWD, "/etc/containers/seccomp.json",
0xc0000ee6b8, 0) = -1 ENOENT (Aucun fichier ou dossier de ce type)
[pid 14835] newfstatat(AT_FDCWD,
"/usr/share/containers/seccomp.json", 0xc0000ee788, 0) = -1
ENOENT (Aucun fichier ou dossier de ce type)
Shouldn't that file be shipped by default too?
Kind regards,
Laurent Bigonville
