Over the past few months, my team have been working to make it easier to create and manage derivative distributions in Launchpad.
Although most of this will be of interest only to distro admins and contributors, we recently released a beta of a new feature that lets you visualize the differences between Ubuntu’s Oneiric series and Debian Sid.
There’s a new portlet on the distroseries page that will list the numbers of packages in both distributions, numbers only in Sid and numbers only in Oneiric. Clicking on the links takes you to pages that show the differences in more detail and allows you to request debdiffs and add comments on the packages.
Coming soon, actual syncing from Debian to Ubuntu. Watch this space!
