For a good while now, I have been obsoleting ebuild attachments on as yet unassigned bug reports and pasting proper unified diffs into comments. I have been doing this so that the maintainers of these ebuilds see the actual changes instead of a giant blob of code that the submitter of the ebuild might want to see in the tree replacing the original ebuild. Previously I also posted a notice asking submitters to post unified diffs instead of entire ebuilds, but this didn't have a noticeable effect so I discontinued that practice in favour of just posting the unified diffs.
Unfortunately, this means that I sometimes get credit for posting such comments. Please make note of the ebuild/diff replacement and attribute the changes correctly to the submitter, not the messenger. I shouldn't be getting the credit for them at all. Regards, jer
