Which is entirely correct.  Re-read what I said about first launch vs
relaunch of the syslogger.  Its stderr will be connected differently in
the two cases, and should be handled differently --- we want the first
launch to try to report problems on its own stderr, but there's no point
after a relaunch.  That's why we pass down redirection_done to it.
