How does that work in practice? Podman is changing the permission bits of files that are synced between the host and the container?

If I create a file with certain permission bits in the container, I'd expect the file to be 100% identical when pulling it over to the host, but maybe that's just "legacy" thinking coming from my docker experience?

What about copying files directly between containers, would that change the permissions as well?

The permissions (rwx) don't change, but the uid/gid is mapped. E.g. uid 0 is the running user outside the container, by uid 1 will be mapped to 100000 (configurable), and say 5000 inside the container is mapped to 105000. I don't remember the exact mapping but it works roughly like that.

Oh, that sounds great! Thank you, that was the information i wanted.

The permission bits are metadata on the fs, the file can still be identical.

Plus, how permissions on a file on the container be identical in the host, if e.g. the groups/users are different?
