Fair enough.

That's not really correct, Michael. It may be your believe, but the fact 
that at the start most of the 3rd party packagers were involved in 
fedora.us is a clear indication that we believed in a single merged 
repository in the long run.

Most existing packagers finally did not believe in the direction fedora.us 
was going and the way it mandated exactly how it was proceeding without 
real input from others outside that inner circle. My experience is that 
that (and of course that RepositoryMixing document) are the real reasons 
why most of us were put off.

Read that document, go back to the situation 2 years ago and ask yourself 
why one of us would be interested to join. Ask yourself why one of us 
would join today ? I think you find more questions than answers. At least 
if you have listened to our concerns then and now.

That's not true. But tell me why we would leave our working environment 
behind for something that had not proven to work (better!) or did not even 
listened to our concerns ? Based on that I can only conclude that it was 
never fedora.us intention to work together.

But that's not really important. The real question is, is there an 
intention now to find some common ground and loose some of the 
duplication efforts or not.

You have to know that of course Fedora is a too limited view (I've 
repeated that before on the fedora.us mailinglists too). Our packages work 
for much more than just Fedora and our userbase is therefor much wider 
than only Fedora and only i386.

This should also be appealing to Red Hat, since having a wide set of extra 
tools and packages that also work for RHEL will only help in selling Red 
Hat in a lot of environments.

Ah, I think I just answered these questions. Fedora is only a small subset 
of what we offer and what we hope to offer. We work not only with the 
Fedora community, but with lots of other communities too, this helps in 
getting more feedback and more users that can give good feedback.

Ok, I thought it was a compliment if I said fedora.us is maturing, but if 
you say it isn't, I'm not going to argue with you. :)

Let me say that the key to fix what you've just summed up is to have a 
subversion/CVS in place and make the commits public (or at least public to 
the packagers). Transparancy is a good way to coherency and to spur 
discussion to things that really matter. An advice from a fellow packager.
