rpm logs?

["Dominick Petracca" <dpetracca gmail com>]

Does rpm maintain logs of all install and removals?

I know we have the rpmpkgs logs in /var/log but how do we know if an install actually went ok?
Meaning is there a way to see the full install log of each package installed (without having to specify the -v at the time of install).
For example, how could I see if someone installed a package but it actually failed one of the post install scripts but still installed...etc.?

Thanks
