+init-system-helpers (1.65.2+deb12u1) bookworm; urgency=medium
+
+  * Add postinst to work around live-build issue on some systems. Needs to
+    be somewhere that will be for sure installed, but all the live-*
+    packages get removed on install, so there's nothing else. This is
+    prio: essential so it's guaranteed to be there to do the cleanup. Can
+    be dropped after Forky ships. (Closes: #1111039)
