Vendor in latest containers/image
Some more features. docker-archive generates docker legacy compatible images Do not create $DiffID subdirectories for layers with no configs Ensure the layer IDs in legacy docker/tarfile metadata are unique docker-archive: repeated layers are symlinked in the tar file sysregistries: remove all trailing slashes Improve docker/* error messages Fix failure to make auth directory Create a new slice in Schema1.UpdateLayerInfos Drop unused storageImageDestination.{image,systemContext} Load a *storage.Image only once in storageImageSource Support gzip for docker-archive files Remove .tar extension from blob and config file names ostree, src: support copy of compressed layers ostree: re-pull layer if it misses uncompressed_digest|uncompressed_size image: fix docker schema v1 -> OCI conversion Add /etc/containers/certs.d as default certs directory Signed-off-by: Daniel J Walsh <dwalsh@redhat.com> Closes: #569 Approved by: mheon
