+Subject: [PATCH] Define and use a safe, reliable test image
+
+The ubi8 image changed some architecture string yesterday and
+broke all our CI on all branches, including podman because
+it too runs bud.bats tests.
+
+Solution: use a safe, reliable, trustworthy test image (the
+one built and used for podman). Because that image does not
+have the same labels, confirm pull using .Architecture
+instead.
+
+We should stop using ubi8 and registry.redhat (#4318). They
+are unreliable. This PR doesn't fix that; it's just an
+emergency patch for one specific CI break. We can use
+this as a basis for future removals of ubi8.
