[Libguestfs] [PATCH 1/2] dib: preserve xattrs and SELinux attributes when exporting as tar

When extracting the content of the guest as tar, save also the extended attributes and the SELinux attributes. This makes sure guests exported as tar, tgz, and as docker image will work fine afterwards. This is what disk-image-create does as well. --- dib/output_format_docker.ml | 3 ++- dib/output_format_tar.ml | 3 ++- dib/output_format_tgz.ml | 4 ++-- 3 files changed, 6 insertions(+), 4 deletions(-) diff --git a/dib/output_format_docker.ml b/dib/output_format_docker.ml index 5303cf9..903ac65 100644 --- a/dib/output_format_docker.ml +++ b/dib/output_format_docker.ml @@ -38,7 +38,8 @@ let docker_run_fs (g : Guestfs.guestfs) _ temp_dir = | Some t -> t in message (f_"Importing the image to docker as '%s'") docker_target; let dockertmp = Filename.temp_file ~temp_dir "docker."
