Hallo,

I notice some disk space discrepancy when running rootless podman containers.
I use dedicated fs for podman storage mountrd to ~/.local/share/containers.
df and du show consistent used disk space:

  island:named [master]> df -h ~/.local/share/containers
  /dev/mapper/sys-containers   117G          84G   32G           73% ~/.local/share/containers

  island:named [master]> sudo du -sh ~/.local/share/containers/storage/{vfs,volumes}
  74G    /home/ivans/.local/share/containers/storage/vfs
  11G    /home/ivans/.local/share/containers/storage/volumes
  island:named [master]> 

But space usage shown by podman system df is about 44% less than reported above:

  island:named [master]> podman system df
  TYPE           TOTAL       ACTIVE      SIZE        RECLAIMABLE
  Images         32          5           39.49GB     25.96GB (66%)
  Containers     7           7           1.85GB      0B (0%)
  Local Volumes  2           2           10.83GB     0B (0%)

Volume space is practically same, it's vfs space (where as I understand images
and containers are located) that differs.

I also run buildah as same user, but buildah ls shows nothing.

I have ran podman system prune, but it reclaimed 0 bytes.

So is this extra space usage expected? Or is it sthing wrong with my storage?

Thanks and regards,
