I'm not bashing Ubuntu, but I find stuff like this
apollock@icarus:~/bin$ grep-status -s Package,Version -F Status "install ok installed" | grep -B 1 ubuntu Package: update-manager Version: 0.42.2ubuntu22-5
in Debian to be a little bit gross.
Sure, our users would have to have been under a rock for the last couple of years to not know about the relationship between Debian and Ubuntu, however I think it blurs the lines a bit to have packages in Debian with "ubuntu" in the version string, and changelog entries relating to distribution names that have no relevance to Debian.
That's my humble opinion anyway. Seeing a package with "ubuntu" in the version string today was the straw that broke the camel's back. I've seen plenty of packages with Ubuntu codenames in the changelogs.
