On startup, check to see if sshd is already daemonized and if so, skip the call to daemon() and do not rewrite the PidFile. This means that when sshd re-execs itself on SIGHUP the process ID will no longer change. Should address bz#2641. ok djm@ markus@. Upstream-ID: 5ea0355580056fb3b25c1fd6364307d9638a37b9
