I am testing the checkpoint functionality of rug on RedHat servers.
It doesn't revert back all packages...
I think I know why though.

When you revert back to a checkpoint ZLM downloads the old RPM's from the ZLM server and downgrades the RPM's (correct me if I am wrong).
So if I try to revert back to the point before any updates were installed (directly after installing the ZLM agent) it cannot find them.
1. The ZLM agent doesn't inform me that it was unable to downgrade all RPM's.
2. If my hypothesis is correct how do I get all the RPM's (all versions) into ZLM?
