The issue that I find here is that there might not be a 1 to 1 mapping. For example, the built binary nova packages in Debian aren't the same as the ones in Ubuntu (not the same number of binaries, etc). So what you'd have to maintain would be a list of package for a certain type of action. For example, rather than a package X is called Y in Ubuntu, and Z in Fedora, you need to store something like: to install nova in Debian, I need: a, b and c packages. > Supporting a new distro is then a matter of adding a translation table > (+ hacking the code to change the right config files, obviously) Well, what we've been trying to do in Debian was to use Debconf for configuring, so we don't need "hacks" to configure (eg: you can use preseeding). That's the ultimate goal, but I'm not sure if we have it done 100% yet. Did you have a look on Ghe Rivero debostack?

You're here talking only for yourself. The "we" isn't everyone, you just happen to be included in it! :) Also, it isn't very nice to see this sentence written again and again in this list. I'd suggest not writing it again, and making the necessary efforts so that there's more involvement in other distros. For example, more testings of Essex in Debian would be appreciated, considering we freeze Wheezy in few days.
