How do you choose a distribution?
I'd like to see a list of all the Linux distros by their mission (like generic, firewall, mail server, free-only, enterprise, virtual machines host, virtual machine guest, audio production, etc.) with basic description and analytics (like first release date, package management system, development activity, people behind the distro (like core team size or, for example "Canonical corporation" for Ubuntu) release cycle description, popularity, etc.). Where can I find such a catalogue?
I've tried distrowatch.com, but couldn't find any classification there. I'd like to be able, for example, to see "all the distros meant specially for a firewall (or a LAMP server) deployment", or "all the distros available as LiveCDs" etc.
