Quick disclaimer: I&#x27;m the author of Tini (thanks for the hat tip, by the way!).<p>Note that for interactive usage, Tini actually hands over the tty (if there is one) to the child, so in that case signals that come &quot;from the TTY&quot; (though in a Docker environment this is an over-simplication) actually bypass Tini and are sent to the child directly. This <i>should</i> include SIGSTP, though I&#x27;m not sure I tested this specifically.<p>That being said, both tools are probably indeed very similar — after all there is little flexibility in that kind of tool! Process group behavior is probably indeed where they differ the most. : )
