Otherwise they might hog resources like /dev/null which can then not be unmounted resulting in their mountpoints (the regular files) not being removable and then the removal of device nodes in run_cleanup (if mmdebstrap is run with --skip=output/dev) will fail. Another potential solution would be to run each hook and apt invocation in its own process namespace but this would require to remount /proc and this in turn would require a new mount namespace as well but we'd like to keep the mount namespace across multiple hooks...
