[Podman] Rootless storage usage

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?
