I have a package resource that gets executed. It is an RPM and has post-install scripts that get run. In some case the RPM;s post-install script fails. This is being handled by the package resource in that it fails as well.

I however want to trap that always call an Exec resource that will do additional checks so we can remove the RPM.

package { 'mypackage':   ensure => installed, }

exec { '/path/to/myscript':
  onlyif  => ...,
  require => Package['mypackage'],

I want the Exec resource to get called always, whether the package resource got run with success or not.

Any idea how to get this accomplished ?

It is my understanding that if the package resource fails, the Exec resource does not get called.

Should I use the notify attribute on the package resource instead ?

Thank You for your time and attention.

What do the post installation scripts do? I would imagine Puppet can do the post installation piece easier than a script can. Then simply order them in your manifests so the package is installed first and the scripts run after the fact.

Thank you for your answer. We thought about that. One problem, we don't have control over the post-install script. It will fire off as a part of the rpm install(we don't author the rpm some other team does that).

that's where Puppet comes in. Do you know what the scripts are supposed to do? Have puppet do it anyway. If the RPM fails then puppet will run, if the RPM succeeds the puppet does nothing.

The problem is that if the rpm is in the resource chain for the later script, the fact that it fails will prevent any resources that require it from running. I'm not sure if this is still true with a notify/subscribe relationship though....
