gconf schema default for ubuntu wallpaper

[Cody A.W. Somerville]

Hello,

 Currently the gconf schema default for the ubuntu wallpaper is set to
warty-ubuntu-final.png. Although we'd like to update this to have a
release agnostic name, unfortunately updating the default gconf schema
does not update existing installation and we can't leave upgrading
users without a desktop wallpaper. Although the name of the file is
less than important, you may have noticed it ends in ".png" - locking
us into png only images for wallpapers which may carry more weight.
So, even if we do update the scheme (and symlink
warty-ubuntu-final.png in the package), it will still lock us into a
certain image type.

 Ideas? Do we decide on an image type and use symlinks? Do we do nothing? etc?

Thanks,
