Martin Meredith blogs that it would be good for other distros also to adopt Malone. Most of the larger distros have established bugzilla’s or their own custom bug trackers, though, so we specifically designed Malone so that it can link to those external bug trackers rather than requiring them to adopt Malone.
Right now, it still requires opening a bug in each of the upstream trackers, which is a pain.
In the future, I think we should see if we can get permission from the upstream bug tracker operators for Launchpad to be able to open bugs directly in their trackers. So, from Launchpad, if we had permission from Mozilla, you should be able to say “this bug in Ubuntu’s Firefox package is also in upstream, please open a bug report for it”. And that should report the bug in bugzilla.mozilla.org, then link it in all the right ways in Malone.
The problem will definitely be the risk of filing unnecessary dups in the upstream tracker. Bugzilla is getting good at getting people to check that the bug they are reporting has not already been reported. We need that same level of defense in Launchpad (though with the ticket tracker slowly improving, we should see more problems starting out there, being handled by the community, and graduating to Malone only once they are verified). And we need a way to make sure that Launchpad does not get a bad reputation for being used to poke dups into upstream bug trackers.
