From 898a8ad28514f90e13b05707a0ead148caa33541 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Tue, 18 May 2021 10:05:03 +0200 Subject: update c/common Update containers common to the latest HEAD. Some bug fixes in libimage forced us to have a clearer separation between ordinary images and manifest lists. Hence, when looking up manifest lists without recursing into any of their instances, we need to use `LookupManifestList()`. Also account for some other changes in c/common (e.g., the changed order in the security labels). Further vendor the latest HEAD from Buildah which is required to get the bud tests to pass.
