+# The previous multipath-tools.prerm maintainer script did not stop the
+# multipathd.service unit, therefore it needs to be stopped here for this
+# specific upgrade case. 
+# "systemctl daemon-reload" is specifically not being called before
+#  deb-systemd-invoke because:
+#   a) it will be called later in the script, before multipathd.service is
+#      started, so let's not call it twice
+#   b) it has system-wide effects, like running all systemd generators again
+#   c) we don't really need the new multipathd.service unit file to stop the old
+#      running daemon. In fact, one could argue it's more correct to use the old
+#      unit file to stop the old daemon.
+# This approach will generate a one-time warning that can be ignored.
