Description

When using ":z" mount option, podman will recursively relabel the SELinux context of all mounted files, causing the "Change" timestamp to be updated, even if the files would have the correct SELinux context to begin with. This is not so great since it tricks tools like git/gitk into thinking that the file content might have changed. Also I guess it inflicts a little more "wear and tear" on the disk.
