Debugging RPM scriptlets with -x

Question

Is there a way to get /bin/sh -x style output from RPM while it's running a scriptlet? I would like to debug RPM installations.

Answer 1

You can put set -x at the beginning of any scriptlet. And rpm -ivvh to install it will give you more than you would want to know.

Answer 2

Try putting an exit 1 in %post scriptlet, then run sh -x on the temporary file left when the upgrade fails (after removing the exit from the temp file).
