+- Avoid running pretrans scripts when running in an instsys:
+  there may be not much installed, yet. pretrans code should
+  be done in lua, this way, it will be executed by the rpm-internal
+  lua interpreter and not be passed to a shell which may not be
+  around at the time this scriptlet is run (bsc#1090292).
