Automatic update for chunkah-0.3.2-1.fc43
Summary
chunkah is an OCI building tool that takes a flat rootfs and outputs a
layered OCI image with content-based layers. It optimizes container image
layer reuse by grouping files based on their content (e.g., by RPM package)
rather than by Dockerfile instruction order.
It is a generalized successor to rpm-ostree's build-chunked-oci command.
Update Information:
Automatic update for chunkah-0.3.2-1.fc43.
