Three comments in debian_install_boot_files.t explain more than the code hides. One narrates the media table the assertions already list. One repeats the nodeset error message and the releases that produce it. One describes what mkinstall used to refuse before the change. A comment states why, once, where the reader cannot re-derive it. Each of the three now carries only the fact the assertions do not show.
