Can't we add a Provides: hammer-cli = %{version} to our spec and query on that? The benefit is that you can also simply run yum install hammer-cli. Similarly, we have foreman-plugin-$plugin provides. That reminds me to check back if Puppet supports this nowadays.

@ekohl we can (and should), but you can't rpm -q on a provides, so in this particular case we'd still be out of luck how to find the version of the installed hammer.

Ah, that's probably also why in the past Puppet didn't support it properly - it used rpm to detect the current state.
