Do you have a transcript of any of the upgrades?  It would be useful
to know what when wrong here, since we do take care to make
init reopen the control channel.
See /var/lib/dpkg/info/sysvinit.postinst lines 9-44 in do_restart().

One question would be if all these systems were running in some
type of container, since we determine the PID of init using
PID="$(pidof /sbin/init || true)"
Is this failing on your systems?  If so, it would be very helpful
to know why, and what we could do to make this more robust.
Should probably be changed to "|| echo 1" as a fallback on failure.

Roger
