As far as how the packaging systems compare, I see yum and apt being similar, except Red Hat and Fedora are the only ones that seem to support 32-bit on 64-bit properly. All the Debian-based distributions have to repackage any 32-bit libraries for 64-bit systems, and you end up with much-reduced support from the repository. Some projects only provide 32-bit packages for some reason or other, and the 64-bit Debian derivatives can't use them. It's ridiculous.
No announcement yet.
