Upstream issue: https://github.com/containers/buildah/issues/6158#issuecomment-2876730732

What were you trying to do that didn't work?

running buildah 1.40 in container on the RH internal GitLab instance runners resulted in

error running subprocess: masking non-directory "/var/tmp/buildah1757143299/mnt/rootfs/proc/interrupts" in mount namespace: permission denied

What is the impact of this issue to you?

Unable to use current buildah on the RH internal GitLab instance runners

Please provide the package NVR for which the bug is seen:

• working: buildah version 1.39.3 (image-spec 1.1.0, runtime-spec 1.2.0)
• broken: buildah version 1.40.0 (image-spec 1.1.1, runtime-spec 1.2.1)

This has been fixed container-selinux 2.237, but needs to be backported
