I've installed Devuan recently on an old laptop wand wanted to pimp it. I saw there were at least two backround packages installed, namely `gnome-backgrounds` and `mate-backgrounds`. To my surprise they don't contain any image... Why is that? And why install background packages at all if they contain no image, contrary to what the package name suggests?

Now it's always possible that I missed something so bear with me.

Thanks in advance,
T.M.
