## What changed - Run the bubblewrap `/proc` mount probe with the minimal read-only filesystem policy instead of the command's filesystem policy and working directory. - Preserve the requested network namespace mode during the probe. - Add coverage that the probe mounts a temporary root and `/proc` without binding the full filesystem.
