It also deploys the default wallpaper configuration from assets/conf/desktop/wallpaper/wallpaper.conf into ~/conf/desktop/wallpaper/wallpaper.conf, which is the file you can edit as a user override. workspace_wallpaper installs wpaperd and deploys your wallpaper files from the repo (./assets/conf/desktop/wallpaper/pictures/) into ~/conf/desktop/wallpaper/pictures.
