branding-ubuntu should use config-package-dev

[Evan Broder]

Binary package hint: branding-ubuntu

branding-ubuntu currently uses hand-written maintainer scripts to create and remove dpkg-diversions at install and uninstall time.

config-package-dev was created to simplify packages that do exactly that (albeit with slightly different paths). We created config-package-dev at MIT in January of 2008 for the Debathena Project (http://debathena.mit.edu/), and it's currently used in 45 separate packages distributed as part of our small distribution. config-package-dev has been in the Ubuntu archives since Intrepid. The package's homepage is at <http://debathena.mit.edu/config-packages/>.

Files that are configured by packages using config-package-dev are installed to the same location as the file they replace, but with a suffix. For example, to replace /usr/share/gnome-games/gnometris/pixmaps/gnometris.svg, you could install your replacement to /usr/share/gnome-games/gnometris/pixmaps/gnometris.ubuntu.svg.

At installtime, the postinst (which is automatically generated by config-package-dev) diverts gnometris.svg to gnometris.ubuntu-orig.svg, and symlinks gnometris.svg to your gnometris.ubuntu.svg. This entire process is undone by the (similarly autogenerated) prerm script when the package is uninstalled, leaving configured files in the exact state they were in before the package was installed.

http://debathena.mit.edu/config-packages/#philosophy and http://debathena.mit.edu/config-packages/#architecture contain more background information which may be useful.

I've updated the branding-ubuntu package to use config-package-dev. My version is attached. You now only have to edit one file to add new branding files. I think this is a huge benefit for future maintainability of the package.

The Debathena team and I have extensive experience using config-package-dev, and would be glad to provide any assistance we can.

Thanks a lot Evan, I'll merge your changes in with some other branding updates I have coming forward. Thanks!

Sorry for being so slow here but by the time I got to looking at this the package had already been updated in a divergent direction and the change is no longer simple to do. As it is we hardly ever update it so it's hardly worth changing the architecture at this point.
