+Subject: [PATCH] Revert "Collect and execute %posttrans scripts delayed
+ (Fate#313506)"
+
+This temporarily reverts commit 40f1e5737baa7082850925573fdd2b45d91deade.
+
+The reason is that the old RPM doesn't have the --noposttrans flag (as already
+established). This was added in this commit:
+
+    https://github.com/rpm-software-management/rpm/commit/23e82afcbc8a9ddde13f0d20c75a549196920139
+
+The commit in libzypp that introduced usage of this is the following:
+
+    https://github.com/openSUSE/libzypp/commit/40f1e5737baa7082850925573fdd2b45d91deade
+
+Following the breadcrumbs (Fate#313506) with a Google search from there leads us to:
+
+    https://bugzilla.novell.com/show_bug.cgi?id=786318
+
+So basically libzypp uses this to move the posttrans scriptlets to after the
+transaction has finished.
+
+As a stopgap measure, we revert that patch in our newer libzypp package to
+avoid that specific error. Once the new RPM is integrated, we can remove the
+revert and get the right posttrans behavior.
