Or we could use what's been proposed by Colin, i.e. ExecStartPre=/usr/bin/sshd -t or my RestartPreventExitStatus=255 The latter has the benefit, that we don't need to parse the config twice and there is no race condition between ExecStartPre and ExecStart where the config file might have been modified. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
