And let them judge if it's worth the adoption or not as a first exercise. Then we can take a decision for Ubuntu.

I believe a patch like the following is needed to avoid this problem: --- a/usr/kinit/ipconfig/main.c +++ b/usr/kinit/ipconfig/main.c @@ -437,6 +437,13 @@ static int loop(void) if (timeout > s->expire - now.tv_sec) timeout = s->expire - now.tv_sec; + + /* Compensate for already-lost time */ + gettimeofday(&now, NULL); + if (now.tv_sec + timeout > start + loop_timeout) { + timeout = loop_timeout - (now.tv_sec - start); + printf("Lowered timeout to match user request = (%d s) \n", timeout); + } } I believe the current behaviour is buggy. This is confirmed when the following line is executed: if (loop_timeout >= 0 && now.tv_sec - start >= loop_timeout) { printf("IP-Config: no response after %d " "secs - giving up\n", loop_timeout); rc = -1; goto bail; } 'loop_timeout' is the user-specified time-out. With a value of 2, in case of error, this line prints: IP-Config: no response after 2 secs - giving up So it thinks that it waited 2 seconds - however, in reality it had actually waited for 10 seconds. The suggested code-change ensures that the timeout that is actually used never exceeds the user-specified timeout.
