Package: podman
Version: 3.0.1+dfsg1-1
Severity: serious


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:


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
