commit cd9556cc84523e2d515a8be2648e2a50fb6b2144

    conf_files_list(): files-add() - do not canonicalize file names
    
    File names in /etc, /run, /usr/lib are sorted/overridden by basename.
    Sorting things like "/dev/null" with the basename "null" in the hash
    of config files breaks the ordering and the overriding logic.
