Tito posted a devfsd error message fix. It's highly deprecated and will

presumably be removed eventually (use udev), but as long as it's in there.

Tito says:

The sense of this patch is to call:
read_config_file_err:
#ifdef CONFIG_DEVFSD_VERBOSE
    msg_logger(((optional ==  0 ) && (errno == ENOENT))? DIE : NO_DIE, LOG_ERR, "read config file: %s: %m\n", path);
#else
    if(optional ==  0  && errno == ENOENT)
        exit(EXIT_FAILURE);
#endif

just after the failure of the  call that set errno ( stat and fopen)
to avoid false error messages.
