Skip steps in uninstall scripts if just an update

[Daniel Neuberger]

Is there any way to tell in your uninstall scripts whether the RPM is
truly being uninstalled or just updated?

The problem is that the pre and post uninstall scripts are run after
the install scripts when using rpm -U.  In other words, what would
work fine if someone did an rpm -e and than an rpm -i might not work
with an rpm -U if the uninstall scripts undo the work of the install
scripts.

Thanks for any help.
