Nearly every file-related function in daemons/*.c is affected: Remove this pair of statements from each affected do_* function: - NEED_ROOT (return -1); - ABS_PATH (dir, return -1); and change the type of the corresponding parameter to "const char *". * src/generator.ml: Emit NEED_ROOT just once, even when there are two or more Pathname args.
