Everytime I am surprised that people don't know that apt-get works on RPM-based distributions and works much better than the alternatives. Especially in a CentOS/RHEL environment where you have various distribution releases running, apt-rpm allows you to use the same apt version and the same apt features across CentOS/RHEL 2.1, 3, 4 and 5.
In an attempt to persuade you to try out apt, let me denounce some myths about the current apt-rpm:
This weekend, after a few weeks of perl updates and fixing our perl SPEC file generator, I broke the perl dependencies and probably upset a few people along the way.
The good news is that we have some new tools for better automating and updating our perl RPM packages and the coming week I hope to finish updating the existing one.
The bad news is that your yum is broken by design. I wish apt was an option, but that possibility looks dimmer and dimmer. (Even though I am still an avid apt user)
