Yeah, but you *should* give a non-sensitive solution. If you use stderr for
logging, you should remove the dup2ing fd 1 to fd 2 line, but it's for
compatibility reasons among various inetd's. By the way inetd (from
netkit-base) actually dup2s fd 1 to fd 2, which will happily puts your logs
to the socket. Why do you want to determine qmail services whether it runs
under tcpserver or not? It's a very heavy compatibility issue.
I'd like to see if DJB himself says anything about the subject. If we want
logging, we should want to do it the official way.
