This code is executed when systemd vmtoolsd.service starts, attached the vmtoolsd.service file. Not seeing this issue before /sbin/telinit becomes a softlink to systemctl. After I did a small change to let loop continue if the first /sbin/telinit fails, then I can see only the first iteration /sbin/telinit got uncaught signal 15, the second, the third iterations /sbin/telinit exit code is 0, no errors.
It seems our session is not terminated when SIGTERM received, or systemctl is quicker and exits, but how could the latter iterations got no errors. > The net effect is the same: before we go down we need to terminate all > processes, of course.
