fix: add --security-opt label=disable to buildah from (2026.1)#115
Merged
Conversation
Prevents SELinux MCS category mismatch when buildah runs inside a podman container. Without this, the nested buildah container gets different MCS labels than the outer container, blocking access to /etc/resolv.conf and causing DNS resolution failures during image builds.
