this patch fixes run_parts when it's called by ifupdown. 1) argv has to be a NULL terminated char* array, not just a string. 2) run_parts now explicitly sets the environment. this environment is populated from the /etc/network/interfaces config file and is needed by the scripts in /etc/network/if-pre-up.d/. when run-parts is called from the command line the environment is taken from the current process. Vladimir Oleynik then wrote: You can simplify this if use: + bb_xasprintf(&buf[0], "/etc/network/if-%s.d", opt); + buf[1] = NULL; + + run_parts(&buf, 2, environ); + free(buf[0]); --w vodz
