Rudder

Currently, when we try and install a package that doesn't exist, apt-get and zypper complain about it (non-zero return code, which leads to an error in Rudder reporting). However, yum doesn't care, and just returns 0, making a "success" or "repaired" report in Rudder.

This is obviously misleading. We should find a way to check if a package exists before running "yum install", and report an error if it doesn't. An idea I have is to do something like "yum search <package name> | grep "^Warning: No matches found for: "" and see what we can do with that. Maybe we can build it into the "package_add_command" of the package_method.
