When unpacking a TAR archive, containerd preserves file's owner: https://github.com/containerd/containerd/blob/main/archive/tar.go#L384 In some cases this behavior is not desired. In current implementation we avoid `Lchown` on Windows. Another case when this should be skipped is when using native snapshotter on darwin and running as non-root user. This PR extracts a generic option - `WithNoSameOwner` (same as `tar --no-same-owner`) to skip `Lchown` when its not required. Signed-off-by: Maksym Pavlenko <[email protected]>
