Hi Brian. Thanks very much for your reply.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt">When I grepped for sighup in the systemd source, I did find the function killall().<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt">The sighup should not be coming from there because my process has argv[0][0] == ‘@’ and there is a check for that in the killall() for-loop (it is done in the static function ignore_proc()).<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt">Also, my process does not have a controlling tty (it is being invoked using the “init” kernel param).<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt">There is no tty shown when I view its details using ps, and I also don’t see any ttys when I do “ls -l /proc/<pid>/fd”.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt">Any other suggestions?<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt">Maybe I should open a github issue for this.<o:p></o:p></span></p>
