Hi All-
Is there an easy way in a package %post script to identify the previous package version? I need to take some actions conditional on what the version was BEFORE the upgrade. Seems like a pretty typical situation...
Sure, write script that tests for previous package, use md5sum on some file if all else fails. That's the most portable solution.
There are triggers that can be added to fire on various versions. Trickier, but doable.
And, with concurrent access in rpm-4.1 and later, you can run a query in %post. Note
carefully that this won't work with versions of rpm that do not support concurrent access,
so add (at least)
Requires: rpm >= 4.1
to your pkg if you attempt rpm -q in %post.
