So what would make sense, imho, would be to just open the bugs to the public once the HW is made public and for sales. This actually _would_ lead immediately to the one single bugzilla. I see no reason why we couldn't do it, other than we are embarassed to show to outsiders our internal struggles in bouncing, squashing, reopening bugs.
Same goes with the publishing of the source code for the kernel. I think it would make much more sense to publish the entire set of git trees with all the history, than just the tarball with the latest source code.
